Subject Write Behind data safety guarantees II
Date Tue, 13 Sep 2016 07:59:38 GMT
Hi,

I've been trying to find information on cache persistence write behind behavior that might
lead to entries not being written to the persistent store.  Most notably: what happens in
the following scenario:


*         Cache 'cache' has two backup copies on nodes A and B respectively and is configured
with persistence to a RDBMS, with write behind activated.

*         Node A collects some write operations, but crashes before the entries can actually
be written.

Will the loss of node A cause node B jump in and write these entries or can ignite "forget"
to write them?

Thank you
