Shashank Gupta commented on OAK-1153:
-------------------------------------
Write throughput comparision between sharded writers and non-sharded writes.
Throughput slightly increased over non-sharded writes.
* Mongo cluster with three shards. Each shard is replica set.
* Non-sharded write throughput.

> Write test to measure throughput on Mongo with multiple reader and writer

> Key: OAK-1153
> URL: https://issues.apache.org/jira/browse/OAK-1153
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: mongomk
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Priority: Minor
>
> To check how raw access to Mongo performs with multiple reader and writers we
> need to have some throughput test.
> It would also server to decide if writing blob in separate databse provides
> any benefit or not. Refer to [1] for discussion around this concern
