Increasing a bucket's ramQuotaMB from the current level. Note, the system will not let you decrease the ramQuotaMB for a couchbase bucket type and memcached bucket types will be flushed when the ramQuotaMB is changed:

Example of a request:

shell> curl -u admin:password -d ramQuotaMB=25 -d authType=none \
    -d proxyPort=11215 http://localhost:8091/pools/default/buckets/bucket_name

The response will be 202, indicating the quota will be changed asynchronously throughout the servers in the cluster. An example:
