Modify a Declared In-Memory Store

For example, you may need to add configuration to allow an In-Memory Store to use memory in external BigMemory hosts when you add servers or deploy Presto in staging or production environments.
2. Click 
Admin Console in the Presto Hub main menu. 3. Click Server to expand this section of the Administration menu.
4. Click BigMemory.
5. Open the BigMemory Cache tap.
The Big Memory Cache tab lists any In-Memory Store configuration files that have already been upload.
6. Select the existing BigMemory data source for this store and click Delete.
