About the Index Self-Optimization Process
The index optimization is a process during which Coveo Cloud consolidates your organization index content. The optimization process recycles orphan identifiers from deleted items and terms to optimize the index structure for faster queries.
The Coveo Cloud platform index features a self-optimizing process that continuously and automatically manages this index compaction. The self-optimization process does not require additional index space.
The self-optimization index process performs the following tasks:
Monitors identifiers that become available when items or terms are deleted from the index.
(When a minimum number of orphan identifiers to recycle are available) At each transaction, for each identifier, clears any remaining references to the identifier and reassigns the identifier to the pool of identifiers that can be used for new items/terms.
The identifier recycling respects processing time and percentage limits to prevent overloading the indexing process.
