Elastic search thread pool setting recommendations
Pega Smart Claims Engine for Healthcare uses elastic search technology for search functionality in several places in the product. For example: Member match, provider match, duplicate check, standalone UI – claim, member search.
The following thread pool settings can be set to scale application performance:
| Threadpool setting | Elastic search default value | Pega's default in Embedded mode(till 8.x) | DASS to configure |
| thread_pool.index.size | # of available processors | 1 | indexing/distributed/index_threadpool_size |
| thread_pool.search.size | int((# of available_processors * 3) / 2) + 1 | 1 | indexing/distributed/search_threadpool_size |
| thread_pool.bulk.size | # of available processors | 1 | indexing/distributed/bulk_threadpool_size |
| thread_pool.force_merge.size | # of available processors | - | indexing/distributed/forcemerge_threadpool_size |
| thread_pool.refresh.max | min(10, (# of available processors)/2) | - | indexing/distributed/refresh_threadpool_size |
All the above settings must be created in the ruleset Pega-SearchEngine. These settings are only applicable to Embedded elastic search mode.
