search head pooling

noun

A way to set up multiple search heads so that they share configuration and user data.

The main reason for having multiple search heads is to facilitate horizontal scaling when you have large numbers of users searching across the same data. With search head pooling, it doesn't matter which search head a user is accessing; all the search heads share configuration information and search artifacts. Search head pooling also helps reduce the impact if a search head becomes unavailable.
