Known Issues

• openGauss cannot monitor file permissions and slow disks. When the file permission is abnormal, the database exits and the corresponding information is recorded in logs. On a slow disk, the response to database operations is slower than usual.

• The read-only mode of the standby node and cascaded standby node is incompatible with the ultimate RTO feature. If the ultimate RTO feature is enabled, disable the read-only mode of the standby node and cascaded standby node.

• Memory Optimized Tables (MOTs) are incompatible with the incremental checkpoint feature. If MOTs are used, disable the incremental checkpoint function.

• LLVM does not support the Arm architecture. When the MOT TPC-C is imported, an LLVM error is reported. To avoid this problem, disable the JIT function using the enable_mot_codegen parameter. You can configure force_mot_pseudo_codegen= true to reduce the impact on TPC-C test performance when the JIT function is disabled.
