Ignite JDBC connection pooling mechanism
Hi All,
we are trying to use HIkari connection pooling with ignite JdbcThinDriver.
we are facing issue as
Any idea what is the supported connection pooling mechanism work with
IgniteThinDriver
ERROR LOG

Re: Ignite JDBC connection pooling mechanism

We solved the problem by removing the complete hikari connection pooling
mechanism.
Instead we use IgniteJdbcThinDataSource (
https://apacheignite-sql.readme.io/docs/jdbc-driver) ,
with appropriate client connector configuration(
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/configuration/IgniteConfiguration.html#setClientConnectorConfiguration-org.apache.ignite.configuration.ClientConnectorConfiguration-
)
After doing a few hit and trials, we concluded ignite does not
require connection pooling in the client side (like we do in RDBMS)
, instead let the Ignite server handle the SQL queries, by providing
appropriate client connection details.

In general it should be ok to use connection pooling with Ignite. Is your
network ok? It look like a connection is being closed because of network
issues.

Re: Ignite JDBC connection pooling mechanism
Posted by Sanjaya Kumar Sahoo <sa...@gmail.com>.
The above idea did not work. The ignite setup is as follows/
Ignite 2.8.1
Hikari 3.4.5
Java 1.8
Spring JdbcTemplate
Apache ignite is in Azure K8S cluster, and the service is being exposed as
a Azure internal load balancer.
The api works well for some time, (*till * *1 hour of restart*), after that
we are getting below error, if we restart then it works for another
approximately 1 hour.
is it not advisable to use a connection pooling mechanism with ignite, if
yes, then what is the best way to serve concurrent requests ? is it kind
creating connection per user request and close once job done ?
Request to help on this we are completely stuck on this use case in
production.

Re: Ignite JDBC connection pooling mechanism
Posted by Sanjaya Kumar Sahoo <sa...@gmail.com>.
Hi,
I truly appreciated the support we are getting from the community.
As of now we don't have a re-producer, The above issue basically comes once
in a while.
The server is up and running, *Note*: The ignite cluster has been installed
in azure kubernetes cluster as statefulset pods.
We have other application pods they frequently talk to ignite.
While analyzing we understood that the application pod which
creating problem, is running with ignite 2.6.0 where as the Ignite server
is 2.8.1 for us
We followed below steps and deployed in production
1- Changed version of Hikari to 3.4.5
2- Ignite core changed to 2.8.1
3- Spring boot was auto configuring jdbc templates (with hikari), we
disabled auto configuration and configured manually.
We deployed the application and we are monitoring, and will publish the
result.
Thanks,
Sanjaya

Re: Ignite JDBC connection pooling mechanism

Hello!
Are you sure that the Ignite cluster is in fact up? :)
If it is, maybe your usage patterns of this pool somehow assign the
connection to two different threads, which try to do queries in parallel.
In theory, this is what connection pools are explicitly created to avoid,
but maybe there's some knob you have to turn to actually make them
thread-exclusive.
Also, does it happen every time? How soon would it happen?
Regards,

I wasn't able to reproduce that hurriedly. What Hikari settings do you have?
Maybe you have a reproducer?

Hi,
What java version do you use? What about Hikari & Ignite versions? Do you
have SSL enabled?
