[infinispan-issues] [JBoss JIRA] (ISPN-3937) Investigate the memory usage of JDBC cache stores when processing a large result set

[Pedro Ruivo (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12987087#comment-12987087 ] 

Pedro Ruivo commented on ISPN-3937:
-----------------------------------

It looks like setting the ```MIN_VALUE``` is not enough (http://dev.mysql.com/doc/connector-j/en/connector-j-reference-implementation-notes.html). However, after reading the docs, the disadvantages are worrying me a little... any other option?

> Iterating over a huge ResultSet with MySQL seems to keep all the rows in memory: https://community.jboss.org/message/854402
> We should investigate whether we can limit the memory usage to a fixed amount and whether this affects other drivers as well.
