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.
