MariaDB Error 1754: Replication Metadata Limit Exceeded
Description
This error occurs during MariaDB replication when a single replication event or transaction modifies data across more databases than the configured maximum limit. While replication might continue, the names of the affected databases will be omitted from the replication event metadata, potentially hindering auditing or troubleshooting of data changes.
Error Message
The number of modified databases exceeds the maximum %d; the database names will not be included in the replication event metadata.
Known Causes
3 known causesExcessive Database Modifications
A single transaction or a series of rapid transactions modify data across an unusually large number of distinct databases within a short period, exceeding the internal or configurable limit for replication event metadata.
Misconfigured Replication Parameters
The `max_mts_updated_dbs_per_event` system variable on the replica is set too low for the current workload, causing the limit to be reached prematurely.
Large-Scale Batch Operations
A single SQL statement or script, such as a global schema migration or a cross-database update, attempts to modify tables in an unusually high number of databases simultaneously.
