# Row Filtering

Verb plans use managed data volume as one of the pricing factors.  As such, there are situations where you may not want Verb to ingest all of your data.  Row filters give you the ability to filter out records that should not be included.

For example, your system may use local deletes where deleted records are flagged for deletion rather than being physically removed.  In this case you may opt to filter all records that are flagged as deleted in your database.  You can do so using the filters section of the data source editor.  This feature allows you to compose additional SQL that will be applied when your database is queried for changes.
