Bharat Viswanadham updated HDDS-1856:
-------------------------------------
Description:
In this Jira following things will be implemented:
# Make the necessary changes for non-HA code path to use Cache and
DoubleBuffer.
## When adding to double buffer, return future. This future will be used in
the non-HA path to wait for this, and when it is completed return response to
the client.
## Add to double-buffer will happen inside validateAndUpdateCache. In this
way, in non-HA, when multiple RPC handler threads are calling preExecute and
validateAndUpdateCache, the order inserted in to double buffer will happen in
the order requests are received.
In this Jira, we shall not convert non-ha code path to use this, as security
and acl work is not completed to use this new model.
