Change Native App Compute Pool

By default, QPR ProcessAnalyzer Native App uses the CPU_X64_S size compute pool. The compute pool size can be changed (for example to CPU_X64_XS) using the following instructions.

The instructions use procedure public.set_compute_pool which is part of the Native App and it recreates application service in a specified compute pool. Application role ADMINISTRATOR is required to run the procedure. The procedure will drop and recreate the application service. Data in QPR ProcessAnalyzer database will be lost - use the snapshot to save and restore data.

-- stop application service
ALTER SERVICE QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE SUSPEND;
CALL QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE!SPCS_WAIT_FOR('SUSPENDED', 600);

-- take snapshot
CREATE SNAPSHOT QPRProcessAnalyzerBackups.Backups.MySnapshot
  FROM SERVICE QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE
  VOLUME "data"
  INSTANCE 0;

-- create new compute pool for application
CREATE COMPUTE POOL QPR_PROCESSANALYZER_COMPUTE_POOL_S
      FOR APPLICATION QPR_PROCESSANALYZER
      MIN_NODES = 1
      MAX_NODES = 1
      INSTANCE_FAMILY = CPU_X64_S
      AUTO_RESUME = true;

-- wait until compute pool is in status IDLE

-- grant permissions to application
GRANT USAGE ON COMPUTE POOL QPR_PROCESSANALYZER_COMPUTE_POOL_S TO APPLICATION QPR_PROCESSANALYZER;

-- call the procedure
CALL QPR_PROCESSANALYZER.PUBLIC.SET_COMPUTE_POOL('QPR_PROCESSANALYZER_COMPUTE_POOL_S');

-- now in Snowflake UI go to application and press 'Activate'
-- wait until activation finished

-- stop application service again to restore snapshot
ALTER SERVICE QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE SUSPEND;
CALL QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE!SPCS_WAIT_FOR('SUSPENDED', 600);

-- restore snapshot

ALTER SERVICE QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE RESUME;
CALL QPR_PROCESSANALYZER.METADATA.QPR_PROCESSANALYZER_SERVICE!SPCS_WAIT_FOR('RUNNING', 600);

-- remove old compute pool
