MEMSQL-OPTIMIZE

MemSQL Ops has been deprecated

Please follow this guide to learn how to migrate to SingleStore tools.

Info

MemSQL Helios does not support this command.

Recommends and optimizes the cluster for maximum performance.

  • If you have numactl installed, set up NUMA based on the number of cores and leaves
  • Recommends that you install new leaves if the number of leaves is less than what is recommended by the NUMA configuration
  • Ensure that the total amount of memory allocated for the leaves is less than the total memory of the machine
  • Set the default number of partitions per leaf to the best possible value based on the number of cores available and the total number of leaves

Usage

usage: memsql-ops memsql-optimize [--settings-file SETTINGS_FILE] [--async]
                                  [--no-numa]
                                  [--memory-percentage MEMORY_PERCENTAGE]
                                  [--no-prompt]

Optimize the cluster for maximum performance.

optional arguments:
  --settings-file SETTINGS_FILE
                        A path to a MemSQL Ops settings.conf file. If not set,
                        we will use the file in the same directory as the
                        MemSQL Ops binary.
  --async               If this option is true, we will exit without waiting
                        for the cluster to be fully optimized.
  --no-numa             If this option is specified, we will not change NUMA
                        settings on any MemSQL nodes.
  --memory-percentage MEMORY_PERCENTAGE
                        The percentage of memory on each machine that we will
                        use for MemSQL.
  --no-prompt           If this option is specified, we will optimize the
                        cluster without prompting for confirmation.
