Coveo Platform 7.0 New Index Self-Optimization
An index periodically needs to recycle identifiers from deleted document and terms to maintain the index compaction and health.
In previous Coveo Platform versions, the optimization process was typically scheduled weekly during off-peak periods to prevent overloading the Coveo Master server during peak hours.
The Coveo Platform 7 new self-optimizing index continuously auto-compacts itself and automatically takes advantage of off-peak periods to optimize the index more aggressively (see About the Index Self-Optimization Process).
The advantages of the new self-optimizing index are:
Eliminates the need to commission an index hard disk that is two times the size of the index
Eliminates the need to set the index in read-only mode during optimization tasks
