To use inbound replication in HeatWave on AWS, the source and its network connection to the replica DB System must have the following configurations.
- The network must be configured to permit replication traffic between the DB System replica and the source server.
- The minimum supported version of MySQL for a replication source is 5.7.9.
- The source cannot be running a higher version of MySQL than the DB System. The replica must be running the same version as, or a higher version of MySQL than, the source.
- If you intend to encrypt the communication between source and replica, the source must be configured to use SSL. See Server-side Configuration for Encrypted Connections.
- The source and the DB System must run with the same
lower_case_table_names
system variable value. See System Initialization Variables - The source must have binary logging enabled, with the system variable

. - The source must use row-based binary logging, with the system variable
binlog_format=ROW
. - For GTID-based replication only: The source must use GTIDs, with the system
