Re: Write-Behind Cache configuration and custom cache store

Rick, writeThrough property enables cache store integration overall, while writeBehindEnabled property controls whether store updates are async or not. So this is correct behavior. As for transactions, write-behind store updates are always non transactional. I.e. you will have a transaction in

Hi Yakov, At first sight, it seems that we can use the same approach for this issue, but in this particular case, I think, the best way to handle OutOfMemoryError is to shutdown the node that could not be activated. Best regards, Slava. 2017-09-06 11:26 GMT+03:00 Yakov Zhdanov
