ArangoDB Server ArangoSearch Options

Threads

arangosearch.commit-threads

Introduced in: v3.7.5

The maximum number of threads to use for asynchronous ArangoSearch commit tasks. The option value must fall in the range [ 1..4 * NumberOfCores ]. Setting it to 0 will automatically choose a sensible number based on the number of cores in the system.

arangosearch.commit-threads-idle

Introduced in: v3.7.5

The minimum number of threads to use for asynchronous ArangoSearch commit tasks. The option value must fall in the range [ 1..arangosearch.commit-threads ]. Setting it to 0 will automatically choose a sensible number based on the number of cores in the system.

arangosearch.consolidation-threads

Introduced in: v3.7.5

The maximum number of threads to use for asynchronous ArangoSearch consolidation tasks. The option value must fall in the range [ 1..4 * NumberOfCores ]. Setting it to 0 will automatically choose a sensible number based on the number of cores in the system.

arangosearch.consolidation-threads-idle

Introduced in: v3.7.5

The minimum number of threads to use for asynchronous ArangoSearch consolidation tasks. The option value must fall in the range [ 1..arangosearch.consolidation-threads ]. Setting it to 0 will automatically choose a sensible number based on the number of cores in the system.

arangosearch.threads

Deprecated in: v3.7.5

The exact number of threads to use for asynchronous tasks (0 == autodetect).

From version 3.7.5 on, the commit and consolidation thread counts should be set separately via the following options instead:

  • --arangosearch.commit-threads
  • --arangosearch.commit-threads-idle
  • --arangosearch.consolidation-threads
  • --arangosearch.consolidation-threads-idle

If either --arangosearch.commit-threads or --arangosearch.consolidation-threads is set, then --arangosearch.threads and arangosearch.threads-limit are ignored. If only the legacy options are set, then the commit and consolidation thread counts are calculated as follows:

  • Maximum: The smaller value out of --arangosearch.threads and arangosearch.threads-limit divided by 2, but at least 1.
  • Minimum: the maximum divided by 2, but at least 1.

arangosearch.threads-limit

Deprecated in: v3.7.5

Upper limit to the auto-detected number of threads to use for asynchronous tasks (0 == use default).

From version 3.7.5 on, the commit and consolidation thread counts should be set separately via the following options instead:

  • --arangosearch.commit-threads
  • --arangosearch.commit-threads-idle
  • --arangosearch.consolidation-threads
  • --arangosearch.consolidation-threads-idle

If either --arangosearch.commit-threads or --arangosearch.consolidation-threads is set, then --arangosearch.threads and arangosearch.threads-limit are ignored. If only the legacy options are set, then the commit and consolidation thread counts are calculated as follows:

  • Maximum: The smaller value out of --arangosearch.threads and arangosearch.threads-limit divided by 2, but at least 1.
  • Minimum: the maximum divided by 2, but at least 1.
