10.4.13. dropddl.js Filter

Within certain replication deployments, there may be occasions where you do not require specific DDL statements to be replicated. For example, you may NOT want to allow TRIGGERS or VIEWS to be replicated, but you do want TABLES, INDEXES, FUNCTIONS and PROCEDURES.

The dropddl filter allows you to configure which, if any, ddl statements to drop from THL and not be replicated.
