Configuring Memory

  • reference
Use REST API to configure custom memory allocation per service.

HTTP Method and URI

POST /pools/default

Description

Allows a custom memory quota to be established for the Multi-Dimensional Scaling (MDS) services Data, Index, Search, Eventing, and Analytics. The Query and Backup Services do not require a memory allocation. If no custom quota was specified during configuration for 1 or more services, those services retain the default allocations. These are the default allocations:

  • 256 Mb for kv (Data Service)

  • 256 Mb for fts (Search Service)

  • 512 Mb for index (Index Service)

  • 256 Mb for eventing (Eventing Service)

  • 1024 Mb for cbas (Analytics Service)

For more information about the maximum memory allocation permitted for a node, see Service Memory Quotas.

Curl Syntax

curl  -v -X POST http://10.144.220.101:8091/pools/default \
  -d memoryQuota=<integer> \
  -d indexMemoryQuota=<integer> \
  -d eventingMemoryQuota=<integer> \
  -d ftsMemoryQuota=<integer> \
  -d cbasMemoryQuota=<integer> \
  -u <username>:<password>

During the process of provisioning a single-node cluster, username and password are required after the administrator has established credentials, as explained in Establishing Credentials.
