ALTER RESOURCE POOL CLASSIFIER

ALTER RESOURCE POOL CLASSIFIER changes the definition of a resource pool classifier.

Syntax

The syntax for changing any resource pool classifier parameter is as follows:

ALTER RESOURCE POOL CLASSIFIER <name> SET (<key> = <value>);

<key> is the parameter name, <value> is its new value.

For example, the following command changes the user to which the rule applies:

ALTER RESOURCE POOL CLASSIFIER olap_classifier SET (MEMBER_NAME = "user2@domain");

The command to reset a resource pool classifier parameter is as follows:

ALTER RESOURCE POOL CLASSIFIER <name> RESET (<key>);

<key> is the parameter name.

For example, the following command resets the MEMBER_NAME setting:

ALTER RESOURCE POOL CLASSIFIER olap_classifier RESET (MEMBER_NAME);

The ALL permission on the database is required. Example of granting it:

GRANT 'ALL' ON `/my_db` TO `user1@domain`;

RANK (Int64) — Optional field that defines the order in which resource pool classifiers are chosen. If omitted, the maximum existing RANK is taken and 1000 is added. Allowed values: a unique number in the range $[0, 2^{63}-1]$ .
RESOURCE_POOL (String) — Required field: name of the resource pool to which queries matching the classifier criteria are sent.
MEMBER_NAME (String) — Optional field specifying which user or group is routed to the given resource pool. If omitted, the classifier ignores MEMBER_NAME and classification uses other criteria.
