-----------------------------------
Summary: Investigate: how to tune down caching in the
KeyValueStore implementations
Key: SAMZA-428
URL: https://issues.apache.org/jira/browse/SAMZA-428
Project: Samza
Issue Type: Improvement
Components: kv
Affects Versions: 0.8.0
Reporter: Chinmay Soman
Fix For: 0.8.0
Currently, we have a 'CachedStore' layer on top of the KeyValueStore
implementation that we use. This might lead to double caching:
i) Once at the CachedStore layer
ii) Possibly cached again in the specific K-V store that we use (for eg:
RocksDB / BDB)
We need the CachedStore layer so that the writes to LoggedStore (if configured)
are done in an efficient manner.
We can then potentially do some config tuning for the K-V store to reduce its
memory footprint and simply write to disk.
