  memsqlctl add-aggregator [flags]

  -h, --help              Help for add-aggregator
      --host string       The cluster-addressable hostname for the node
  -p, --password STRING   The SQL password for connecting to MemSQL
      --port PORT         The cluster-addressable port for the node (default 3306)
      --user string       The SQL user for connecting to MemSQL (default "root")

Global Flags:
  -c, --config FILE_PATH                     Path to the memsqctl config file
      --default-install-dir DIRECTORY_PATH   Path to the default install directory
  -j, --json                                 Print output in JSON format
      --node-metadata-file FILE_PATH         Path to the node metadata file
      --parallelism POSITIVE_INTEGER         Maximum amount of operations to be run in parallel
      --ssl-ca FILE_PATH                     Path to the CA certificate file in PEM format to authenticate the MemSQL server certificate
      --timeout duration                     Maximum time for operation to complete (e.g., 30s, 10m, 1.5h)

This command must be run from the same host that the master aggregator is currently running on.

After memsqlctl connects to the node specified by the user, it runs the query ADD AGGREGATOR user:password@host:port on the master aggregator.

This command is interactive unless you use either the --yes or --json flags to override interactive behavior.

The memsqlctl add-aggregator command is equivalent to the memsql-admin add-aggregator command.


The following is the standard output for the add-aggregator command.

$ sudo memsqlctl add-aggregator --host ""
memsqlctl will perform the following actions on the local master aggregator on port 3306:
  · Run `ADD AGGREGATOR root:****@`
