ATLAS-5227: Support disabling composite index
> Support disabling composite index
> ---------------------------------
>
> Key: ATLAS-5227
> URL: https://issues.apache.org/jira/browse/ATLAS-5227
> Project: Atlas
> Issue Type: Task
> Reporter: Pinal Shah
> Assignee: Pinal Shah
> Priority: Major

> *Description:*
> This Jira is to support disabling the active index in janusgraph.
> For Example : For ddl.queryText , isIndexable=true.
> *This patch handles the support to make any attribute to isIndexable=false.*
> *Possible Improvement to Disable unnecessary Indexes:*
> # *Write Latency* will drop significantly because JanusGraph no longer has
> to create a secondary index entry for that massive string.
> # *HBase Stability* will improve because we might stop hitting "Key Size
> Limit" exceptions.
> # *Storage Savings:* It will not create indexes
> *Explanation:*
> To properly remove an index, we need to follow below updated in sequence
> # *DISABLE_INDEX:* Sets state to {{{}DISABLED{}}}. The index is no longer
> used for queries and stops receiving updates.
> # *DISCARD_INDEX:* Removes all data from the index storage. The index state
> becomes {{{}DISCARDED{}}}.
> # *DROP_INDEX:* Removes the index definition from the JanusGraph schema
> entirely.
> But performing *DISCARD_INDEX* and *DROP_INDEX actions* can be too expensive
> when there is huge indexed data. Hence this patch only handles
> *DISABLE_INDEX*
