ftsMemoryQuota

      +

      The ftsMemoryQuota setting controls the maximum usable memory, in MiB, available to the Search Service on each node in your cluster. This RAM allocation applies to each node that has the Search Service in 1 of its Service Groups.

      You can configure the ftsMemoryQuota from the Couchbase Server Web Console at any time.

      If you’re using the Search Service as the only Service on a node, set the ftsMemoryQuota to 80% or less of the total available RAM for that node. This guideline leaves enough RAM for your operating system to manage its on-demand filesystem cache. The search process memory maps your index files to support fast access to indexed content.

      Configure the ftsMemoryQuota

      To configure the ftsMemoryQuota setting:

      1. From the Couchbase Server Web Console, go to Settings.

      2. Under Memory Quotas, in the Search field, enter a value, in MiB, for the total amount of RAM you want to allocate to the Search Service for each node in your cluster.

      3. Click Save.
