Subject questions on frequency and timing of async replication between DCs
Date Fri, 11 Nov 2011 22:10:58 GMT
I have cross dc replication set up using 0.8.7 with 3 nodes on each DC by
following the +1 rule for tokens.
I am seeing an issue where the insert into a DC happened successfully but
on querying from cli or through Hector, i am not seeing the data being
returned. i used cli on every node of both DCs and every node returned
blank. So basic question is where is my data? CL.WRITE=ONE, CL.READ=1. RF =
DC:2, DC:2
Apart from checking the data directory size on each DC to verify that
cross-dc replication has happened, what others steps can i take to verify
that cross dc replication is happening successfully? What tuning params can
i control with regard to cross-dc replication? (frequency? batch size?, etc)

would greatly appreciate any help.
