I have following MariaDB 10 replication setup.
Server A MariaDB 10 (master), Server B MariaDB 10 (master), Server C MariaDB 10 (slave/master), Server D MariaDB 10 (slave).
A and B are getting new data from different sources (Percona Server, AWS RDS) using Tungsten replicator and replicate this data to C. C replicates to D.
- mysqldump from A and B
- import to C and configure multi-source replication
- mysqldump from C
- import to D configure replication
After a while A and B are getting new data, but this data is not replicating neither to C or D (from C).
If I go to A or B and create fake tables and insert fake data everything replicates up to D.
No errors in mysql error log, no errors in replication status.
What can be possible wrong?
