Description

Resolution:

Sync/Async replication only changes how fast a client receives confirmation. 


Async - client does not wait to ensure all nodes have written the value to memory. 


Sync - replication waits until all nodes (owner and replica) has a copy.


Sync/Async persistence - Sync persistence blocks the write operation until the disk write completes. Async persistence will dispatch the file write and continue. File writes are flushed to disk every 10 seconds. This is configurable through SpaceDef setFileSyncInterval.
