All Implemented Interfaces:

Action

public class MongoDBSyncDatabaseAction
extends SyncDatabaseActionBase

An action class responsible for synchronizing MongoDB databases with a target system.

This class provides functionality to read data from a MongoDB source, process it, and then synchronize it with a target system. It supports various configurations, including table prefixes, suffixes, and inclusion/exclusion patterns.

Key features include:

• Support for case-sensitive and case-insensitive database and table names.
• Configurable table name conversion with prefixes and suffixes.
• Ability to include or exclude specific tables using regular expressions.
• Integration with Flink's streaming environment for data processing.

Note: This action is primarily intended for use in Flink streaming applications that synchronize MongoDB data with other systems.
