How can I reload data after Recovery the space with mirror ?

Hello, everyone.

I'm on making proposal doc for my customer, and I have one question for Fail Over part..

So, I'll use Polling Container for processing specific data and persist that result to database.

My question is.. if space is crashed, (all servers are down because of disaster), the space should have some data which is not persist inside database.

So, for this case, that data will be disappeared and we cannot recovery that data after Recovery our space...

That is right ? or do we have any solution for protect non persisted data..

Please let me know.

Thank you very much.

Best Regards, Chris Cho

A space in production environment running on multiple different physical servers.
A space partition would have one primary and at least one backup. If one of these fails a new one will be created preserving the SLA defined during the deploy time.
The chance all servers will have total failure in the same time is very small. Only in this case the in-fligt transactions there were not replicated from the Mirror (async persistence) will get lost. If you want to address this very low chance you can configure persistene without the mirror working in sync replication mode. See: http://wiki.gigaspaces.com/wiki/display/XAP91/DirectPersistency

Once the space is restarted it will load all relevant data back from the database. You can tune this activity via custom initial load. See: http://wiki.gigaspaces.com/wiki/display/XAP91/ExternalDataSourceInitialLoad
