How It Affects Your App
The error ER_NDB_CANT_SWITCH_BINLOG_FORMAT indicates that the MySQL server is unable to switch the binary log format. This can have a significant impact on the application as it may prevent the application from writing to the binary log, which is necessary for replication and other operations. Additionally, the application may be unable to read from the binary log, which can lead to data loss or corruption. As a result, the application may become unstable or unusable.
