| Description |
|
The causal_reads feature depends on the MASTER_GTID_WAIT function to work properly. Currently, the code does this by modifying the SQL to wait for the condition and fail if it does't work. As the waiting is done in the SQL, this doesn't work with prepared statements. This limitation is not currently documented in the parameter documentation. |
