MySQL 1650

This error occurs when a slave is configured to ignore the server ID of the master. It is a warning that the slave will not replicate any changes made by the master.

How It Affects Your App

MySQL 1650 ER_SLAVE_IGNORE_SERVER_IDS is an error that occurs when a slave server is configured to ignore the server IDs of the master server. This can have a significant impact on an application as it can prevent the slave server from replicating data from the master server. This can lead to data loss or inconsistency between the master and slave servers, which can cause application errors or data corruption. Additionally, it can lead to replication delays, which can cause the application to be unresponsive or slow.
