2.2.8 Reload Tables

HeatWave MySQL can reload all tables.

Press CTRL+C to copy
 
mysql> CALL sys.heatwave_reload ([options]);

options: {
     JSON_OBJECT("key","value"[,"key","value"] ...)
          "key","value": {
          ["only_user_loaded_tables",{true|false}]
          ["output",{"normal"|"silent"}]
          }
}

Use key-value pairs in JSON format to specify options. HeatWave uses the default setting if there is no defined option. Use NULL to specify no arguments.

The options include:

• only_user_loaded_tables: Enabled by default. The procedure only reloads user tables. If false, the procedure reloads user and system tables.

• output: Defines where to send the output. Permitted values are:

  • normal: The default. Produces summarized output and sends it to stdout and to the heatwave_autopilot_report table. See Section 2.7.9, “Autopilot Report Table”.

  • silent: Sends output to the heatwave_autopilot_report table only. See Section 2.7.9, “Autopilot Report Table”. The silent output type is useful if human-readable output is not required; when the output is consumed by a script, for example.
