MQTT V3 Plug-in Reference

"tableAutoTimeStampIndex"

• Boolean
• Optional
• Defaults to "true"
• Values: "true" or "false"

When set to true, an index will be created on the "ts" field in the table. Set to false to prevent the creation of the index on the auto timestamp field named "ts".

Create this index only when you have an application connecting directly to the c-tree database that runs queries using the timestamp.

If "tableRetentionPeriod" is set to a non-zero value, then this index will be created regardless of the value of this property.

"AlterPersistenceTopic" can add the auto-timestamp later.

• If table retention is being used, the automatic timestamp index is created automatically and cannot be removed. If you want to remove the auto timestamp index, you must not use table retention or you must disable it.
