Driver (*): Select Database type (MYSQL, MSSQL, Oracle, Postgres, MongoDB, ClickHouse, Snowflake)
Port (*): Host server port number
Host IP Address (*): IP Address
Username (*): Username for Authentication.
Password (*): Password for Authentication.
Database Name (*): Provide the Database name.
Table Name: Provide the table name to read the data.
Refresh rate: The value of this field has to be provided in seconds. It refreshes the master table and fetch the changes in every cycle of the given value. For example, if refresh rate value is given as 3600 seconds, it will refresh the master table in every 3600 seconds and fetch the changes.
Connection Type: This option will show if the user selects MongoDB from the Driver field. A User can configure the MongoDB driver via two connection types (Standard or SRV) that are explained below:
Standard - Port field does appear with the Standard connection type option.

The data of previous event is taken as inputDF as the table name in the query field of enrichment component as shown in the above query example.
Remove [works like an inner join]– This option completely removes the row If any row of incoming data is not matching with query condition of the lookup table. Only passes the matching records.
Blank – This option sets blank for the cell of a row if complete incoming data from the in-event and matching rows from the lookup table.
