What is accelerated data model?
When a data model is accelerated, a field extraction process is added to index time (actually to a few minutes past index time).
This greatly speeds up search performance, but increases indexing CPU load and disk space requirements.
Extracted data model fields are stored in the high-performance analytics store (HPAS).
