Explain Storage engines in Couchbase server?
Couchbase Server actually has a tail-append storage design which is unaffected to the corruption of data, abrupt loss of power or OOM killers. Data is written in the data file in an append-only manner, which enables Couchbase to do sequential write-ups for an update, and it also provides an optimized access pattern and also enhanced access patterns for disk Input/Output.
