Roger Hoover commented on SAMZA-428:
------------------------------------
[~jkreps], thanks for the reply. Sorry if this is already answered somewhere
in the docs but how does a user sync her batches with the framework batches? I
want the framework checkpoints to line up with my batches.
> 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.
