1. Configurable Primary Key ⏳

When you define a primary key, instead of receiving an update event when the column changes, you will receive two events:

• A delete event with the old value of this column (and other fields).
• An insert event with the new value of this column (and other fields).

2. Custom Conditions ⏳

You can configure conditions, and if a database row does not match the criteria, you will not receive any event.

In the case of an update:

• If the row previously matched the criteria but the new row does not, you will receive a delete event.
• If the row previously did not match the criteria but the new row does, you will receive an insert event.

3. Partial Fields ✅

Ability to listen only to certain columns in your table. If no changes occur in one of these columns, you will not receive any event.
