Setting disk I/O priority

Setting disk I/O priority

The disk I/O priority for a bucket is set with the /pools/default/buckets/[bucket-name] URI and the threadNumber setting.

HTTP method and URI

To set the maximum of thread workers, use the threadsNumber option. To specify high priority, assign eight (8) threads. To specify low priority, assign three (3) threads. Default: threadsNumber=3 . Only high or low priority are allowed.

POST /pools/default/buckets/[bucket_name]

The threadNumber parameter is used to specify disk I/O priority for a bucket.

Important: When editing bucket properties, be sure to specify all bucket properties. If a bucket property is not specified (whether or not you are changing the existing value), Couchbase Server may reset the property to the default. Even if you do not intend to change a certain property, re-specify the existing value to avoid this behavior.


Curl request syntax:

curl -v -X POST -u [admin]:[password] \
  http://[localhost]:8091/pools/default/buckets/[bucket-name] \
  -d threadsNumber=[3 | 8] 


The following example sets the threadsNumber for the default bucket to eight (8), which is high priority, from the default of three (3), which is low priority.

curl -v -X POST -u Administrator:password \ \
  -d threadsNumber=8
