------------------------------------------

Hello, [~slukyanov]

 

Sorry, wrong ticket in the message. The correct ticket is IGNITE-12826 (which 
mentioned in the ticket description).

IGNITE-12826 adds ability to set fetchSize in the JdbcDialect.

Please, see 
**https://github.com/apache/ignite/commit/50547b9b59f1e1a0da1f117877cdb17e8aa155d7#diff-ad3364370e42cec87e83ef2922179827R684

> JDBC's PreparedStatement accepts a fetchSize parameter which defines how many 
> rows will be loaded from the DB at a time. Currently the only way to change 
> that is by specifying it in a custom implementation of the 
> JdbcDialect::fetchSize method (and even then it seems not be be used in some 
> cases).
> Would be good to have a fetchSize property in all of JDBC-based cache stores.
