Hi,
We are facing a serious issue with CAS in a multi DC setup and I wanted
to get some input on it from the forum.
We have a Column family which stores counts for the number of events our
application receives. When the counts reach a certain threshold,
there is another process which kicks in. The issue that is happening is,
sometimes when concurrent events come in 2 Data Centers, both the events read
the same count
and increment it to the same value which causes the next process to not kick in.
When concurrent events come in the same DC, this does not happen, because in
this case, the CAS explicitly fails for one of them.
However, in case of Multiple DCs this is not happening. Has anyone faced a
similar issue and is there any resolution to this?? I was unable to find any
open Jira on this.
Thanks,
Charu
