taking more time while reading records.

[Shuvendu Das]

Hi,

We came across a situation where it is taking 10 time more time while
reading records.
  Our initial grid size is 390,746 (count)
  Grid size increased to 7,297,301 (count)
  Now it is taking 10 times more time.

Regards

Shuvendu

Re: WebConsole does not see cluster

[KJQ]

All right, im completely confused at this point.

Trying to follow this thread:
http://apache-ignite-users.70518.x6.nabble.com/Agent-not-able-to-connect-tt21714.html#a21745

  

*I see this in the console startup:*
ignite-console_1  | 00:36:34 0|index| Start listening on 127.0.0.1:3000

I have, for now, exposed all of the ports "i think" so I can try the agent
outside of the containers:

  ignite-console:
image: apacheignite/web-console-standalone
expose:
  ...
ports:
  - 3000:3000
  - 3001:80

  server:
ports:
  - 3080:3080

The server has the REST API, exposed on 3080, and I can access it with curl.

*I then run the agent:*
./ignite-web-agent.sh --server-uri http://localhost:3001 --node-uri
http://localhost:3080

*And get this:*
Agent configuration:
User's security tokens: 4BDV
URI to Ignite node REST server: http://localhost:3080
URI to Ignite Console server  : http://localhost:3001
Path to agent property file   : default.properties
Path to JDBC drivers folder   :
/Downloads/ignite-web-agent-2.6.0/jdbc-drivers
Demo mode : enabled

This is all running on one machine but different docker containers (from
compose)

WebConsole does not see cluster

[KJQ]

Hello.

I am trying to get the Dockerized WebConsole running but no matter what I do
it does not recognize any clusters.  

I am running the Web Agent from one of my nodes with the REST (maven)
dependencies.

I can see the nodes coming up when I start my services and using the CLI I
can inspect the cluster fine.
Topology snapshot [ver=4, servers=4, clients=0, CPUs=16, offheap=6.2GB,
heap=2.5GB]

*Running the agent I see:*
URI to Ignite node REST server: http://localhost:3080
URI to Ignite Console server  : http://ignite-console
[2018-08-12 22:23:08,341][INFO ][main][AgentLauncher] Connecting to:
http://ignite-console
[2018-08-12 22:23:08,441][INFO ][EventThread][AgentLauncher] Connection
established.
[2018-08-12 22:23:08,524][INFO ][EventThread][AgentLauncher] Authentication
success.
[2018-08-12 22:23:08,751][INFO ][pool-1-thread-1][RestExecutor] Connected to
cluster [url=http://localhost:3080]

I can curl the REST API using 'http://localhost:3080/ignite?cmd=version'
from the console instance to the node running the REST module and get back
the version.
"response": "2.6.0"

But, no matter what I seem to do the WebConsole does not recognize the
cluster - what am I doing wrong here?

Re: The Apache Ignite Book

[luqmanahmad]

Dear Shamim,

I have recently developed a network segmentation plugin for Apache Ignite
project. It would be nice if you can add some stuff related to plugins as
well. Please see [1] for more information.

Free Network Segmentation (akas split brain) plugin available

[luqmanahmad]

Hi all,

Recently I was working on a project which required a very large number of
cluster over 700 nodes and we were encountering with split brain problem. To
overcome that problem I have recently developed the plugin for network
segmentation which can be downloaded from [1].

This can be taken as a gift as it was a much needed functionality which was
missing from the open source version. At the moment there are two
segementation resolvers are available. I am still thinking of writing one
for TcpIp depending on the time.

Any problems with the plugin, please let me know. Happy coding

Re: ODBC Driver compile error

Hi Linus,

I had the same error when I was trying to compile with openssl 1.1. Compiling 
with openssl1.0 solved the issue for me..

Subject: ODBC Driver compile error [External]

Hi all,

I've been trying to compile the ODBC Driver under a fairly standard
Debian system. Ignite installed from the deb on the Ignite website,
although I've also tried the latest GIT release with the same results.

Google found another user with a similar issue back in March on this
list, but no resolution was reported back.

The make fails with the following errors listed below. Is there
particular gcc/g++/openssl version requirement which isn't obvious?

Any pointers would be appreciated,

Re: The Apache Ignite Book

[Павлухин Иван]

Hi Shamim,

In 1st chapter Introduction among Ignite possible usages it is mentioned:
"From version 2.5 Apache Ignite will support transactions at SQL level"
It is not true. Transactional SQL was not released yet. There is plan to
release it in near future, but as for me it is better to not mention
concrete future versions for
features which are not released yet.
