Hi,
Please have a look at topic below to get an estimation of memory usage:
http://apache-ignite-users.70518.x6.nabble.com/off-heap-memory-usage-tc19282.html
I will check the warning later, it looks strange to me.
Thanks,

Hi,
Below is my code and result where I am trying to query IgniteRDD through SQL
statement with scala at Zeppelin.
First I use restful API to put a pair of data(key=10, val=45) into Ignite cache.
%python
import requests
requests.put("http://127.0.0.1:8080/ignite?cmd=put=10=45=zeppelincache;)
Thanks Alexey for quick response.

Hi,
I see the same message with 2.1 release. 2.3 does not have it.
I will check 2.1 source code later.
Do you use 2.1 release?
Thanks,
Alexey

Hi Andrey,
Thanks for the info. Could you also let me know how to migrate the data from
2.1 to 2.3. Are there any APIs/feature which I can use to do that?

Local store means store, that resides only on one node. No other nodes see

If you don't have local stores in cluster(only distributed ones), then it
will be the only db connection within transaction opened.

Hi,
In 2.3 some configuration methods are deprecated and will be removed in
next major release (ignite-3.0).
You can safely continue to use old-style configuration, but of course we
recommend to switch to new-style if possible to be able to use new features.
I'm not sure 2.3 can support old
Default memory region is always there even if you add more user-defined
data regions. If you are not going to use it at all and not happy with the
memory still allocated to the default region you can specify a smaller
amount of memory allocated for the default region as described here

Hi Team,
I am testing Ignite cache persistent configuration on version 2.30.
I am experiencing strange behavior and it is not consistent behavior.
Could you please suggest me how to configure and test persistent behavior?
Thanks and Regards,

Hi!
Forget about it, it was my fault, when you use a String as a value in a
cache (and use indexing), it requires that you have Lucene jar's in the
classpath, I didn't have that.

Hello Ilya!
Thanks for the advice with "JOIN TABLE".
Can you recommend something for the configuration and diagnostics of the
Apache Ignite cluster?
For example, what metrics should I look for when the response time starts to
grow?

Hi, Andrey!
Actually, data could be persisted not on tx initiating node, but on
primary(I.e. we have partitioned cache and local cache) .
Additionally, data would be persisted on backup node if you enable the
corresponding flag.
