SQL Server Replication Source

CDAP-19354: The default setting for the snapshot transaction isolation level (snapshot.isolation.mode) is repeatable_read, which locks the source table until the initial snapshot completes. If the initial snapshot takes a long time, this can block other queries. 

...

1. Configure SQL Server with one of the following transaction isolation levels:

• In most cases, set snapshot.isolation.mode to snapshot.

• If schema modification will not happen during the initial snapshot, set snapshot.isolation.mode to read_committed.

For more information, see Enable the snapshot transaction isolation level in SQL Server 2005 Analysis Services.

2. After SQL Server is configured, pass a Debezium argument to the Replication job. To pass a Debezium argument to a Replication job in CDAP, specify a runtime argument prefixed with source.connector, for example, set the Key to source.connector.snapshot.isolation.mode and the Value to snapshot.

...
