Execute Blocking Snapshot

Execute a blocking snapshot for the specified source.

Blocking snapshots pause streaming during the snapshot operation and use Debezium's initial snapshot process. They are useful for:

• Snapshotting keyless tables (which incremental snapshots cannot handle)
• Snapshotting large tables faster than incremental snapshots

Warning: Streaming will be paused during the snapshot operation. Note: additional_conditions filters are not supported for blocking snapshots.
