Performance Considerations

[#1]

Users must opt into the Extended Meta feature and only specific types of meta should be extended. Extended meta can have an impact on the following areas (but not limited to):

Database Size

Extended meta refers to data written to core databases. Increasing the maximum size of the meta can result in shorter retention periods as session sizes grow. This can lead to more frequent occurrences of meta database size rolls and shorter retention periods, especially in environments with high amounts of extended meta.

Query Performance

The performance of queries or expensive operations can be adversely affected. In an environment with many rules or queries containing operations like "contains" and "regex", these operations will naturally take longer to run when used with longer values.

Aggregation

Aggregation is the process of downloading data. Since Extended Meta can increase the size of meta data per session, each round of aggregation may potentially take longer.
