Hi, Can we configure some column-families (or keyspaces) in Cassandra to perform as a pure in-memory cache?
The feature should let the memtables always be in-memory (never flushed to the disk - sstables). The memtable flush threshold settings of time/ memory/ operations can be set to a max value to achieve this. However, it seems uneven distribution of the keys across the nodes in the cluster could lead to java error no-memory available. In order to prevent this error can we overflow some entries to the disk? Thanks, Kapil
