> Is there a particular reason for using TLOG replica types? We used to use NRT replica types, but we switched to TLOG a year or two ago in order to prioritize indexing speed above all else, understanding that it might take a while for query results to be identical across replicas. This is the first time we've had a use case where we need to query immediately after indexing. Had we known then what we know now, maybe we wouldn't have switched... but that's hindsight I guess.
With an NRT replica type, do you know if we issue a commit does it apply to all replicas? We're not too far down the path that we couldn't switch back, and I assume that the effect would be minimized if we did so. However, I'd like to know that the issue would be completely GONE, not just reduced in frequency if we did switch back... Thanks!
