Redis slaves should be able to reply to clients while SYNC-ing with master #352

Open GoogleCodeExporter opened 8 years ago

Currently Redis replication is non-blocking from the point of view of the 
master, but it is blocking from the point of view of the salve.

This can be a problem with some use case. For instance when there is a slave 
farm in order to scale reads, if the master will go out the salves will lost 
the link and will try to resync at the same time, even in a context where 
serving old data is ok.

The solution is the ability to configure slaves so that they can act in 
different ways while SYNC-ing with the master, for instance:

slave-sync-behavior error # Will report an error -ERR SYNC with master in 
progress
slave-sync-behavior serve-old-data # Will continue serving old data while the 
SYNC is in progress
