[jira] [Commented] (OAK-3253) Support caching in FileDataStoreService

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-3253?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130256#comment-15130256 ] 

Chetan Mehrotra commented on OAK-3253:
--------------------------------------

[~shgupta@adobe.com] If caching is enabled would it also mean that async upload would be enabled by default? If yes then it would be better to disable it by default as that would pose problem in clustered deployment where a binary uploaded on one node might not be accessible on other cluster node.

> FDS on SAN/NAS storage is not efficient as it involves network call. In OAK. indexes are stored SAN/NAS and even idle system does lot of read system generated data. 
> Enable caching in FDS so the reads are done locally and async upload to SAN/NAS
