I'm afraid we don't have a separate Jira ticket for this issue. Basically because this memory overhead consists of two parts:
1. Object serialization protocol. 2. Cache and index data structures. The first one is compact enough and usually should not be a problem, the second is almost impossible to optimize without big changes (like replacing the whole data structure). So usually we try to improve memory consumption as part of other tasks. For example in 1.7 we've updated H2 database version and have done some related work to decrease this overhead. Now we are thinking about some big architectural changes for 2.0, I hope they will help here even more. BTW, 1.7 is already available for download: https://ignite.apache.org/download.cgi#binaries Sergi 2016-08-07 12:53 GMT+03:00 Jason <[email protected]>: > hi Sergi, > > would you like to help add the related JIRA tasks here so that people who > concern can easily check its status? > > Thanks, > -Jason > > > > -- > View this message in context: http://apache-ignite-users. > 70518.x6.nabble.com/Question-about-GridGain-will-typically- > add-around-200-bytes-overhead-to-each-entry-tp6411p6835.html > Sent from the Apache Ignite Users mailing list archive at Nabble.com. >
