Re: proposed design for thin client SQL management and monitoring (view running queries and kill it)

Vladimir,

Two of these are not a big deal. We just need to invest more time for
development and during the design phase so that people need to consult the
docs rarely.

Let's use a more loose name such as "node".

That's a good point. Syntax of both running and killing queires commands
should be tightly coupled. We're going to name a column if running queries
IDs somehow anyway and that name might be resued in the WHERE clause of
KILL.

Should we discuss the syntax in a separate thread?

Re: [DISCUSSION] Design document. Rebalance caches by transferring partition files

[Eduard Shangareev]

Sergey,

>If I understand correctly when there is a continuous flow of updates to the
page already transferred to receiver checkpointer will write this page to
the log file over and over again. Do you see here any risks of exhausting
disk space on sender's side?

We could track the set of page which are in log file to avoid this issue
(any concurrent hash set would work fine);

> What if some updates come after checkpointer stopped updating log file?
How
these updates will be transferred to the receiver and applied there?

Temporary wal file on the receiver from the original approach should cover
this case.

Re: [DISCUSSION] Design document. Rebalance caches by transferring partition files

[Sergey Chugunov]

Eduard,

This algorithm looks much easier but could you clarify some edge cased
please?

If I understand correctly when there is a continuous flow of updates to the
page already transferred to receiver checkpointer will write this page to
the log file over and over again. Do you see here any risks of exhausting
disk space on sender's side?

What if some updates come after checkpointer stopped updating log file? How
these updates will be transferred to the receiver and applied there?

Re: [DISCUSSION] Design document. Rebalance caches by transferring partition files

[Eduard Shangareev]

So, after some discussion, I could describe another approach on how to
build consistent partition on the fly.

1. We make a checkpoint, fix the size of the partition in OffheapManager.
2. After checkpoint finish, we start sending partition file (without any
lock) to the receiver from 0 to fixed size.
3. Next checkpoints if they detect that they would override some pages of
transferring file should write the previous state of a page to a dedicated
file.
So, we would have a list of pages written 1 by 1, page id is written in the
page itself so we could determine page index. Let's name it log.
4. When transfer finished checkpointer would stop updating log-file. Now we
are ready to send it to the receiver.
5. On receiver side we start merging the dirty partition file with log
(updating it with pages from log-file).

So, an advantage of this method:
- checkpoint-thread work couldn't  increase more than twice;
- checkpoint-threads shouldn't wait for anything;
- in best case, we receive partition without any extra effort.

Re: Lightweight profiling of messages processing

[Vladimir Ozerov]

Alexey,

I would say that to implement this feature successfully, we first need to
clearly understand specific scenarios we want to target, and only then plan
implementation in small iterations. Please take in count the following
points:
1) Splitting by message type might be too fine-grained thing for the first
iteration. For example, we have N different message types processed in a
system pool. Add several messages causing long-running tasks (e.g. invoke),
and deque time will grow for all other message types for the same queue. I
think we can start with a simpler metrics - per-pool queueing time, pool
throughput, pool task latencies. This would be enough for a wide number of
use cases. We may expand it in future if needed.
2) Some IO statistics were already implemented as a part of IGNITE-6868
[1]. See TcpCommunicationSpiMBeanImpl. You may find it useful for your task.
3) Public API should be designed upfront. Normally it should include JMX
and system SQL views (e.g. like [2]). JMX is useful for external tools, SQL
views allow access to performance data from all platforms all at once. This
is critical.
4) It should be possible to enable/disable such metrics in runtime.
Probably infrastructure from IGNITE-369 [3] might be reused for this
purpose (see GridCacheProcessor.EnableStatisticsFuture)
5) IO access statistics are already under development [4]. First part will
be merged very soon.
5) Performance effects must be measured extremely carefully in all modes
(in-memory, persistence, background/log_only/fsync), because you are likely
to change very performance sensitive code pieces. We had a lot of
performance issues when implementing IGNITE-6868 [1].

Vladimir.

Re: Lightweight profiling of messages processing

Clarification: p.5 is about buffer pool and disk access statistics, not
network.

[jira] [Created] (IGNITE-10426) [ML] Spread parameter isKeepRawLabels across all models

[Aleksey Zinoviev (JIRA)]

Aleksey Zinoviev created IGNITE-10426:
-

 Summary: [ML] Spread parameter isKeepRawLabels across all models
 Key: IGNITE-10426
 URL: https://issues.apache.org/jira/browse/IGNITE-10426
 Project: Ignite
  Issue Type: Improvement
  Components: ml
Affects Versions: 2.8
Reporter: Aleksey Zinoviev
Assignee: Aleksey Zinoviev
 Fix For: 2.8


Currently, a few models has the parameter isKeepRawLabels and threshold to 
change predicted value to one of class labels 1 or 0.

Discuss this in dev-list and think how to solve this task to optimize 
MultiClassModel

Possible solution:
 * add these methods to common model
 * add this method to MultiClassModel and use reflection to check this 
parameter in apply method for example

[jira] [Created] (IGNITE-10425) Node failed to add to topology due to problem with detecting local Address

[Max Shonichev (JIRA)]

 Summary: Node failed to add to topology due to problem with 
detecting local Address
 Key: IGNITE-10425
 URL: https://issues.apache.org/jira/browse/IGNITE-10425
 Project: Ignite
  Issue Type: Bug
Affects Versions: 2.5
Reporter: Max Shonichev
 Fix For: 2.8


When localhost has resolvable DNS name to 127.0.0.1, running two nodes on with 
"localHost" property set to 127.0.0.1 might result in following exception:
{noformat}

Caused by: class org.apache.ignite.spi.IgniteSpiException: Failed to add node 
to topology because remote node is configured to use loopback address, but 
local node is not (consider changing 'localAddress' configuration parameter) 
[locNodeAddrs=[prtagent07.gridgain.local/0:0:0:0:0:0:0:1, 
prtagent07.gridgain.local/127.0.0.1, /172.25.2.7, 
/2001:0:9d38:6abd:24c2:3fcd:53e6:fdf8], rmtNodeAddrs=[127.0.0.1],

This looks extremely silly, both nodes are started locally and still can't 
connect to each other

Re: Service grid redesign

[Vyacheslav Daradur]

We had the private talk with Nikolay Izhikov, Vladimir Ozerov, Alexey
Goncharuk, Yakov Zhdanov, Denis Mekhanikov, Dmitriy Pavlov and I would
like to share the summary with the community:

The architecture of the implemented deployment process looks good in
general, but the following points should be improved:
* The new implementation of service processor implementation should be
moved to a new class;
* A new system property should be introduced to allow users to switch
to old implementation in case of errors;
* Introduced service deployment failures policy should be removed from
current PR and should be implemented as a different task with detailed
discussion on dev list to avoid unexpected behavior;
* The word "exchange" should be removed from classes names to avoid
confusion with PME classes.
* Single/full messages should include containing only deployment
process-related information only (instead of all service) to reduce
messages size;

Thanks all! I'll let you know once I fix the notes.

Re: Lightweight profiling of messages processing

[Alexey Kukushkin]

Hi Alexei,

Did you consider general-purpose APM
 tools
like free InspectIT  or commercial
DynaTrace  or AppDynamics
?

Java APM tools do not require writing code or even instrumenting Ignite
binaries: you just attach them as javaagent
 to
Ignite JVM and then you can configure "sensors" to track whatever API you
want. APM tools collect metrics from the sensors and provide sophisticated
analysis tools.

DynaTrace claims they have 2%-7% overhead (depending on application) but
you can always detach the tool if you do not always need it in production.

I did not try APM for Ignite myself but it might work well.

Lightweight profiling of messages processing

[Alexei Scherbakov]

Igniters,

At work I often have to solve performance issues with Ignite cluster
without having access to source code of running user application.

Looks like Ignite have limited capabilities to identify bottlenecks without
extensive profiling on server and client side (JFR recording , sampling
profilers, regular thread dumps,  etc), which is not always possible.

Even having profiling data not always helpful for determining several types
of bottlenecks, on example, if where is a contention on single
key/partition.

I propose to implement new feature, like lightweight profiling of message
processing.

The feature will allow to have view on message processing statistics for
each node and for all grid nodes.

In short, it's necessary to track each message execution in executors and
record execution statistics like synchronous execution time in executor
thread and waiting time in queue.

Full description:

1. Implement detailed tracking of message waiting in queue and actual
processing by executors with splitting to several time bins. Example of
detailed statistics for each processed message:


Processing time(%)
 Message   Total Average(ms)
 < 1 ms   < 10 ms< 30ms< 50ms   < 100ms   < 250ms   <
500ms   < 750ms  < 1000ms  > 1000ms

Re: Code inspection

[Maxim Muzafarov]

Igniters,

I propose to make inspection configuration default on the project
level. I've created a new issue [1] for it. It can be easily done and
recommend by IntelliJ documentation [2].
Thoughts?


Vyacheslav,

Can you share an example of your warnings?
Currently, we have different inspection configurations:
- ignite_inspections.xml - to import inspections as default and use it daily.
- ignite_inspections_teamcity.xml - config to run it on TC. Only fixed
rules in the project code are enabled. Each of these rules are marked
with ERROR level.

Re: Brainstorm: Make TC Run All faster

[Павлухин Иван]

Roman,

Do you have some expectations how faster "correlated" tests
elimination will make Run All? Also do you have a vision how can we
determine such "correlated" tests, can we do it relatively fast?

But all in all, I am not sure that reducing a group of correlated
tests to only one test can show good stability.

[jira] [Created] (IGNITE-10422) Make {{ignite_inspection.xml}} configuration default on the project level

[Maxim Muzafarov (JIRA)]

Maxim Muzafarov created IGNITE-10422:


 Summary: Make {{ignite_inspection.xml}} configuration default on 
the project level
 Key: IGNITE-10422
 URL: https://issues.apache.org/jira/browse/IGNITE-10422
 Project: Ignite
  Issue Type: Task
Reporter: Maxim Muzafarov


IntelliJ IDEA can perform static code analysis by applying _inspections_ to the 
project code. The inspection analysis process can be easily run from both the 
IDE and the command line. The command line usage of IntelliJ IDEA inspections 
already configured as daily [Inspections(Core) 
TeamCity|https://ci.ignite.apache.org/viewType.html?buildTypeId=IgniteTests24Java8_InspectionsCore&branch_IgniteTests24Java8=%3Cdefault%3E&tab=buildTypeStatusDiv]
 suite. This approach has proven its convenience and efficiency as part of the 
_TC.Bot_.

As for the next step, I propose to improve personal productivity of writing 
code by making *{{ignite_inspection.xml}}* configuration default on the project 
level.

According to [IntelliJ IDEA 
documentation|https://www.jetbrains.com/help/idea/code-inspection.html] the 
inspection profile should be placed to *{{/.idea/inspectionProfiles}}* 
with name *{{Project_Default.xml}}*. This project profile will be shared and 
accessible for the team members via VCS by default.

Note.
The build and test procedure of Apache Ignite project will remain IDE 
independent.

[jira] [Created] (IGNITE-10420) Enable ignored test in "Cache 1" test suite.

[Andrew Mashenkov (JIRA)]

Andrew Mashenkov created IGNITE-10420:
-

 Summary: Enable ignored test in "Cache 1" test suite.
 Key: IGNITE-10420
 URL: https://issues.apache.org/jira/browse/IGNITE-10420
 Project: Ignite
  Issue Type: Sub-task
  Components: general
Reporter: Andrew Mashenkov


"Cache 1" TC suite actually runs IgniteBinaryCacheTestSuite.

It looks like we can merge IgniteBinaryCacheTestSuite and IgniteCacheTestSuite 
as the last one is never run separately.

IgniteBinaryCacheTestSuite has ignored test that never run. 
Let's enable these tests and mute them with certain Jira ticket if there is any 
issue.

Re: Historical rebalance

[Seliverstov Igor]

Vladimir,

I think I got your point,

It should work if we do the next:
introduce two structures: active list (txs) and candidate list (updCntr ->
txn pairs)

Track active txs, mapping them to actual update counter at update time.
On each next update put update counter, associated with previous update,
into a candidates list possibly overwrite existing value (checking txn)
On tx finish remove tx from active list only if appropriate update counter
(associated with finished tx) is applied.
On update counter update set the minimal update counter from the candidates
list as a back-counter, clear the candidate list and remove an associated
tx from the active list if present.
Use back-counter instead of actual update counter in demand message.

Re: MVCC test coverage.

[Roman Kondakov]

Vladimir, Andrey,

as you mentioned this approach has several disadvantages. I can name a 
few of them:


1. This new MVCC suites will be triggered in "long" runs at night - this 
means developers will not receive feedback about MVCC problems 
immediately - they will have to wait until their commit will be merged 
to master and than triggered at night build. It may lead to permanent 
problems in master branch.


2. Developers should always keep in mind that all tests they add will be 
run twice: for MVCC mode and non-MVCC mode. And if they don't want their 
tests run twice, such tests should be added to exclude map in the 
according MVCC suite. Due to the fact this is not the obvious rule and 
we do not have any possibility to control this process, I expect this 
rule will be violated very often. This lead us to double runs of non 
MVCC-relevant tests.


3. MVCC has became a full-fledged feature of Apache Ignite. Each 
developer should take it into account when contributing to project. Mvcc 
case should be considered in each feature as well as other atomicity 
modes: transactional and atomic. Proposed approach removes the need for 
the developer to think of MVCC at all. Everybody will assume that if 
they've added atomic and transactional tests, their job is done, beacuse 
MVCC test should run automatically. IMO this is not good.



Of course, proposed approach has an obvious advantage: it is very fast. 
We can adopt old tests to MVCC case in a couple weeks. So, it is a good 
temporary solution.


As a possible long-term solution I would propose the following:

1. Do not inherit MVCC suites from non-MVCC suites, but instead refactor 
it - i.e. extract common logic to the basic abstract class and run this 
tests with different atomicity modes - MVCC and non-MVCC.


2. Notify developers about TRANSACTIONAL_SNAPSHOT atomicity mode has the 
same importance as other modes and it should be considered in the same 
way as other.


3. To deal with the dramatically increased number of tests, RunAll suite 
could be split into two variants: RunAll(full) and RunAll(fast) as 
discussed on dev-list several times. Full suite runs all tests, fast 
suite runs only a subset of tests (or all tests but with the smaller 
timeouts -it is under discussion). One of the proposed ways [1] - is to 
extract only significant, representative tests from the entire suite, 
and run this small subset on "fast" RunAll's. In this case if we have a 
significant test in MVCC suite - we do not have to wait night build 
until this test is checked - because if the test is significant - it in 
the "fast" run by default.

Hi Andrey,

Thank you for bringing this question to the list. I already reviewed this
PR and it looks good to me. But I would like to hear more opinions from
other community members regarding the whole approach.

One important detail - we are going to create new suites as a child classes
of existing suites with irrelevant tests excluded manually. This way if a
new test is added to existing cache suite, it will be automatically added
to TC suite as well, and we will see potential MVCC issues in a nightly
build. This is critical thing to keep MVCC mode on par with “classical”
transactions.

I am not 100% happy with the fact that we will know about new failures only
after problematic commit is pushed. But I do not see how to improve it
without extending Run All time for another 30 hours. This will do more harm
than good. So proposed solution looks like a good pros-cons balance at the
moment.

Vladimir.

Hi Igniters,

As you may already know, MVCC transaction feature will be available in
upcoming Ignite-2.7.
However, MVCC Tx feature is released for beta testing and has many
limitations and we a going
to improve stability and integrations with other features in future
releases.

We can reuse existed transactional cache tests and run them in Mvcc mode to
get much better test coverage with small looses.
Here is a ticket for this IGNITE-10001 [1].

This mean we will have twice more "Cache Tests" and get TC runs some
longer.
To reduce new Mvcc cache suites impact and save TC time we are going to
1. Include new tests to nightly suite only, this will allow us to put our
ears to the ground.
2. Exclude non-tx tests and non-relevant tx cases and aggressively mute
tests for unsupported features integrations.

I've implement a PR to one of  tasks [2] as an example how it can be done.

Technical details:
1. Introduced a new FORCE_MVCC flag and created a child "Mvcc Cache 2"
suite for "Cache 2" test suite with FORCE_MVCC flag on.
2. Implemented a hook that change TRANSACTIONAL cache atomicity mode to
TRANSACTIONAL_SNAPSHOT if FORCE_MVCC flag turned on.
This allow us to check MVCC mode without creating new

Re: Historical rebalance

[Seliverstov Igor]

Ivan,

1) The list is saved on each checkpoint, wholly (all transactions in active
state at checkpoint begin).
We need whole the list to get oldest transaction because after
the previous oldest tx finishes, we need to get the following one.

2) I guess there is a description of how persistent storage works and how
it restores [1]

Vladimir,

the whole list of what we going to store on checkpoint (updated):
1) Partition counter low watermark (LWM)
2) WAL pointer of earliest active transaction write to partition at the
time the checkpoint have started
3) List of prepared txs with acquired partition counters (which were
acquired but not applied yet)

This way we don't need any additional info in demand message. Start point
can be easily determined using stored WAL "back-pointer".

Re: Historical rebalance

[Vladimir Ozerov]

Just thought of this a bit more. I we will look for start of long-running
transaction in WAL we may go back too far to the past only to get few
entries.

What if we consider slightly different approach? We assume that transaction
can be represented as a set of independent operations, which are applied in
the same order on both primary and backup nodes. Then we can do the
following:
1) When next operation is finished, we assign transaction LWM of the last
checkpoint. I.e. we maintain a map [Txn -> last_op_LWM].
2) If "last_op_LWM" of transaction is not changed between two subsequent
checkpoints, we assign it to special value "UP_TO_DATE".

Now at the time of checkpoint we get minimal value among current partition
LWM and active transaction LWMs, ignoring "UP_TO_DATE" values. Resulting
value is the final partition counter which we will request from supplier
node. We save it to checkpoint record. When WAL on demander is unwound from
this value, then it is guaranteed to contain all missing data of
demanders's active transactions.

I.e. instead of tracking the whole active transaction, we track part of
transaction which is possibly missing on a node.

Will that work?

[jira] [Created] (IGNITE-10416) Revisit GridCacheAbstractTest childs.

[Andrew Mashenkov (JIRA)]

Andrew Mashenkov created IGNITE-10416:
-

 Summary: Revisit GridCacheAbstractTest childs.
 Key: IGNITE-10416
 URL: https://issues.apache.org/jira/browse/IGNITE-10416
 Project: Ignite
  Issue Type: Bug
  Components: general
Reporter: Andrew Mashenkov


We have a lot of test inherited from GridCacheAbstractSelfTest, that code is 
complicated and a bit outdated regarding to the fact JUnit 4/5 is coming. 
Moreover,  starting grid from class constructor made test muting tricky and 
disabling cacheStore (which is always enabled by default) doesn't looks 
straightforward in child classes.

 

We should revisit all its childs and check if such parentness is correct.

 

First candidates are:
 # Test has own "start grid routine", but implements gridCount() method just as 
a dummy.
 # Before/After methods do not call parent methods. This should be handled 
carefully.
 # Test that doesn't expect a feature to be used, but enabled in 
GridCacheAbstractSelfTest.
E.g. usually, rebalance test doesn't expect cacheStore to be enabled.

Re: New API for changing configuration of persistent caches

[Vladimir Ozerov]

Ed,

I think most questions around API will go away once we understand how users
are going to use it. Can you provide several examples of properties which
we think are going to be changed often, along with concrete example of API
usage (native API, control.sh, whatever we think important)?

Personally, with my SQL-oriented bias, I do not understand why we call
operation "restart" and why we need API with CacheConfiguration at all. In
SQL world we have ALTER TABLE command which may include one or several
changes for the given table ("cache" in our terms). And in the vast
majority cases user change only one property in a single command. Rarely -
several properties. Extremely rare - redefine the whole table.
Next, not all changes require "restart" at all. In SQL terms we call
operations "ONLINE" when there is no need to stop cache operations for a
long time, and "OFFLINE" otherwise. For Ignite more than half of properties
can be changed "ONLINE" - events flag, write-behind parameters, partition
loss policy, rebalance properties, etc.. I would say that this "change",
not restart.

Thoughts?

Re: Historical rebalance

[Vladimir Ozerov]

Igor,

Could you please elaborate - what is the whole set of information we are
going to save at checkpoint time? From what I understand this should be:
1) List of active transactions with WAL pointers of their first writes
2) List of prepared transactions with their update counters
3) Partition counter low watermark (LWM) - the smallest partition counter
before which there are no prepared transactions.

And the we send to supplier node a message: "Give me all updates starting
from that LWM plus data for that transactions which were active when I
failed".

Am I right?
