Summary: Rework ignite binary metadata exception for ease of
troubleshooting
Key: IGNITE-12106
URL: https://issues.apache.org/jira/browse/IGNITE-12106
Project: Ignite
Issue Type: Bug
Components: cache, persistence
Affects Versions: 2.7.5, 2.7.6
Reporter: Denis Magda
Fix For: 2.7.6
An exception of this kind happens regularly and its message doesn't suggest why
it took place and how to fix the issue:
{noformat}
Cannot find metadata for object with compact footer: 2097659979
{noformat}
See this thread for more details:
http://apache-ignite-developers.2346864.n4.nabble.com/Metastore-disappears-in-Docker-on-restarts-td43107.html
As a solution, let's rework this exception to ensure that the way like that
"Ignite work directory might be cleared on restarts. Ensure that IGNITE_HOME
doesn't point to a temp folder or any other folder that is destroyed/erased on
restarts. Presently, IGNITE_HOME points to..."

Stop the node 2. Delete all persistence files of the node (best to clear Ignite working directory, storage directory, WAL and WAL archive directories) 3.

Summary: Wrong off-heap size is reported for a node
Key: IGNITE-9305
URL: https://issues.apache.org/jira/browse/IGNITE-9305
Project: Ignite
Issue Type: Task
Affects Versions: 2.6
Reporter: Denis Magda
Fix For: 2.7
Was troubleshooting an Ignite deployment today and couldn't find out from the
logs what was the actual off-heap space used.
Those were the given memory resoures (Ignite 2.6):
{code}
[2018-08-16 15:07:49,961][INFO ][main][GridDiscoveryManager] Topology snapshot
[ver=1, servers=1, clients=0, CPUs=64, offheap=30.0GB, heap=24.0GB]
{code}
And that weird stuff was reported by the node (pay attention to the last line):
{code}
[2018-08-16 15:45:50,211][INFO
][grid-timeout-worker-#135%cluster_31-Dec-2017%][IgniteKernal%cluster_31-Dec-2017]

^-- Node [id=c033026e, name=cluster_31-Dec-2017, uptime=00:38:00.257]
^-- H/N/C [hosts=1, nodes=1, CPUs=64]
^-- CPU [cur=0.03%, avg=5.54%, GC=0%]
^-- PageMemory [pages=6997377]
^-- Heap [used=9706MB, free=61.18%, comm=22384MB]
^-- Non heap [used=144MB, free=-1%, comm=148MB] - this line is always the
same!
{code}
Had to change the code by using {code}dataRegion.getPhysicalMemoryPages(){code}
to find out that actual off-heap usage size was
{code}
>>> Physical Memory Size: 28651614208 => 27324 MB, 26 GB
{code}
The logs have to report the following instead:
{code}
^-- Off-heap {Data Region 1} [used={dataRegion1.getPhysicalMemorySize()},
free=X%, comm=dataRegion1.maxSize()]
^-- Off-heap {Data Region 2} [used={dataRegion2.getPhysicalMemorySize()},
free=X%, comm=dataRegion2.maxSize()]
{code}
If Ignite persistence is enabled then the following extra lines have to be
added to see the disk used space:
{code}
^-- Off-heap {Data Region 1}: used={dataRegion1.getTotalAllocatedSize() -
dataRegion1.getPhysicalMemorySize()}
^-- Off-heap {Data Region 2} [used={dataRegion2.getTotalAllocatedSize() -
dataRegion2.getPhysicalMemorySize()}]

It complies with our assumption that the node should be recovered soon and there is no need to waste CPU/memory/networking resources of the cluster shifting the data around. However, there are always edge cases. I was reasonably asked how to trigger the rebalancing within the baseline topology manually or on timeout if: * It's not expected that the failed node would be resurrected in the nearest time and * It's not likely that that node will be replaced by the other one. Until we embedd special facilities in the baseline topology that would consider such situations we can document the following workaround. A user application/tool/script has to subscribe to node_left events and remove the failed node from the baseline topology in some time. Once the node is removed, the baseline topology will be changed, and the rebalancing will be kicked off. -- This message was sent by Atlassian JIRA (v7.6.3#76005)

Summary: Document how to rollback transactions to let PME complete
Key: IGNITE-8171
URL: https://issues.apache.org/jira/browse/IGNITE-8171
Project: Ignite
Issue Type: New Feature
Components: documentation
Reporter: Denis Magda
Fix For: 2.5
Some Ignite operations provoke partition map exchange process within Ignite to
ensure the partitions distribution state is synchronized cluster-wide. Topology
update events and a start of a new distributed cache are examples of those
operations.
When the partition map exchange starts, Ignite acquires a global lock at a
particular stage. The lock can't be obtained until pending transactions are
running in parallel. If there is a transaction that runs for a while, then it
will prevent the partition map exchange process from the start freezing some
operations such as a new node join process.
This property allows to rollback such long transactions to let Ignite acquire
the lock faster and initiate the partition map exchange process. The timeout is
enforced only at the time of the partition map exchange process.
See {{TransactionConfiguraion}} and
{{IgniteTransactions.localActiveTransactions and withLabel}} methods.

Fix For: 2.6
Presently, Ignite doesn't ship {{SHOW TABLE}} command. Thus, it's not clear how
to get tables and schema structures in Ignite.
Until this command is not supported we have to explain that:
* Many tools use JDBC and ODBC metadata related parameters can pull that
information out of there and present it to an end user. For instance, SQLline
utilizes {{!table}} command that gets data from JDBC metadata methods. DBeaver
utilizes the same approach.
* Let's create {{Database Administration}} section under SQL reference
(https://apacheignite-sql.readme.io/docs/sql-reference-overview) and presently
list approaches supported by various tools (sqlline, dbeaver, etc) and how to
get the same information from the drivers.

allows setting up affinity collocation and demonstrate meaningful SQL queries
with joins:

First, this script can be used as is and executed in any SQL tool such as
SQLline.

script, create a file that will store DDL statements and turn INSERTS into a

Users don't get how to use table and schema name in Ignite:
[https://stackoverflow.com/questions/48723946/apache-ignite-querying-a-cache-through-an-sql-driver]
The confusion comes from the interpretation of term "case-insensitive". All SQL
databases work this way:
1) If I create some object and define its name without quotes, a database will
convert it to upper case (sometimes lower case). Then if I query this object
without quotes, a query is also transformed to upper case. This is what I call
"case-insensitivity" - it doesn't matter how you refer to this object, it works
still.

2) If I create an object with quotes, then the database doesn't convert it to
upper case, and the original name in quotes is *the only way* to access the
object:
CREATE TABLE "myTable" -> CREATE TABLE myTable
SELECT FROM myTable -> SELECT FROM MYTABLE -> *{color:#ff}FAIL!{color}*
SELECT FROM MyTable -> SELECT FROM MYTABLE ->
*{color:#ff}FAIL!{color}*SELECT FROM "myTable" -> SELECT FROM myTable -> OK
Now back to Ignite case. Our schemas are case-sensitive. so the only way to
access it is through quotes:
CREATE SCHEMA "cacheName"; // This is what Ignite does internally
SELECT * FROM "cacheName".myTable -> OK
SELECT * FROM cacheName.myTable -> *{color:#ff}FAIL!{color}*
Our users know this, and all their queries are written with schema names in
quotation marks. Now consider what would happen should we change schema names
to case-insensitive mode:
CREATE SCHEMA cacheName;
SELECT * FROM "cacheName".myTable -> *{color:#ff}FAIL, +all old quries
start to fail!+{color}*
SELECT * FROM cacheName.myTable -> OK, now it works

Some of the problems are: * Each "version" is just a copy of the previous one. When fixing something, you have to update all the versions. * No good way to review changes. * "Propose edit" functionality is a not suitable for review. You can only accept or reject an edit, no way to communicate with a contributor, etc * There is no way to prevent Google from indexing old documentation versions.

Summary: Enable Ignite cache events per cache
Key: IGNITE-7346
URL: https://issues.apache.org/jira/browse/IGNITE-7346
Project: Ignite
Issue Type: Improvement
Components: cache
Reporter: Denis Magda
Fix For: 2.4
Whenever a cache event from {{EventType.EVTS_CACHE}},
{{EventType.EVTS_CACHE_REBALANCE}} or {{EventType.EVTS_CACHE_QUERY}} set is
enabled and a listener is registered, the cluster will accumulate and send out
events for all the deployed caches.
Such behavior brings down performance especially if hundreds and thousands of
caches are used while the user is interested in the monitoring of specific
caches.
Let's add a configuration property like {{CacheConfiguration.setEventsEnabled}}
to enable or disable the events per cache. The events will be enabled by
default to comply with existing behavior.

Apache Ignite binary releases still include “fabric” word in their names:
https://ignite.apache.org/download.cgi#binaries
For instance, this is a full name of the previous release -
apache-ignite-fabric-2.3.0-bin.
It’s a little oversight on our side because the project has not been positioned
as a fabric for a while.
Remove “fabric” from the name and have the binary releases named as -
apache-ignite-{version}-bin.

Cache operations executed from a client-side are not accounted in average time
metrics. Use this reproducer [1] performing the following:
* Start a server node [2] that will report
{{getAveragePutTime}}/{{getAverageGetTime}} metrics in a loop.
* Start a client node [3] that will report the same metrics and do cache
updates/reads.
Both nodes show {{0}} for those metrics.

Reporter: Denis Magda
Fix For: 2.4
If an SQL schema and cache is created with CREATE TABLE command and a user
wants to use key-value APIs creating its own custom key class, then (at least)
the key class's affinity field forced to be written in upper-case.
Steps to reproduce using the project attached:
* start a node with {{./ignite.sh ../examples/config/example-ignite.xml}}.
* create {{City}} table using {{ignite_world.sql}}. SQLline is one of the
quickest ways: https://apacheignite-sql.readme.io/docs/sqlline
* Run {{KeyValueDataProcessing}} to catch the exception below
{noformat}
Exception in thread "main" class
org.apache.ignite.binary.BinaryObjectException: Binary type has different
affinity key fields [typeName=demo.model.CityKey, affKeyFieldName1=COUNTRYCODE,
affKeyFieldName2=countryCode]
at
org.apache.ignite.internal.binary.BinaryUtils.mergeMetadata(BinaryUtils.java:987)
{noformat}
If fact {{CityKey}} names the affinity field in the same way as in CREATE TABLE
- {{countryCode}}.
Next, run {{KeyValueBinaryDataProcessing}} to spot another weird thing:
* BinaryObject key accepts `countryCode` as the affinity field name.
* If to print our a binary object value then all the fields are in the
upper-case (they were not defined this way in CREATE TABLE):
{noformat}
demo.model.City [idHash=1613627715, hash=-1386587499, DISTRICT=Noord-Holland,
POPULATION=711200, NAME=Amsterdam]
{noformat}
