PolarDB-X CDC is a core component of PolarDB-X which is responsible for global binary log generation, publication and subscription.
With PolarDB-X CDC, PolarDB-X database can provide binary log fully compatible with MySQL binary log, which can be consumed seamlessly by MySQL binary log tools. And it can play the role of MySQL slave through MySQL Replication protocol.
The core features of PolarDB-X CDC include the following:
-
Global Binlog: Merges the original Binlog generated by all PolarDB-X DN nodes into a single global queue, providing a logical Binlog stream that ensures transaction integrity and orderliness, and can provide stronger data consistency guarantees.
-
Binlog-X: Generates multiple logical Binlog streams in real-time to solve the bottleneck problem of Global Binlog in large-scale clusters, and provides stronger distributed scalability capabilities.
-
Replica: Compatible with the MySQL Replication protocol, providing the ability to serve as a MySQL or PolarDB-X standby database.
The PolarDB-X CDC is a builtin component of the PolarDB-X.
Try PolarDB-X CDC by following these steps:
- Start a PolarDB-X
See CDC Node Creation Guide to create a PolarDB-X instance with CDC nodes.
- Try MySQL Binary Log Commands
PolarDB-X is fully compatible with MySQL binary log related commands, such as SHOW BINARY LOGS, SHOW BINLOG EVENTS,
etc. All commands can be found in
the PolarDB-X Binlog Commands Introduction.
- PolarDB-X as MySQL Slave
PolarDB-X supports MySQL Replica related commands, such
as CHANGE MASTER TO，START/STOP/RESET SLAVE，SHOW SLAVE STATUS, etc. you can use PolarDB-X as MySQL slave, refer
to Replica Reference Manual for command
details.
