Is there no optional memstore flush anymore? I recall in 0.19 the memcache would flush every so-often and you could configure this period (optional cache flush interval).
Digging through now, I don't see it in 0.20. Is this mechanism no longer supported? Due to a couple of mixups, our stop cluster, take backup, restart cluster mechanism had stopped running for a while. So we were not force-flushing, nor generating enough data to flush. Then we had a crash and I realized that the on-file stores were missing writes from weeks ago. I eventually got the data back from the WAL. cheers, -clint
