RisingWave Community - What could be causing the cluster meta nodes to crash while creating SINKs in a RisingWave cluster?

The cluster meta nodes crashing while creating SINKs in a RisingWave cluster could be due to ETCD's high-demanding requirement for the quality of the disk it is running on.
ETCD may crash or lose connection with RisingWave due to transient disk latency spikes, leading to cluster instability.
One possible solution is to increase the memory quota for ETCD and adjust CPU resources if high CPU usage is observed.
Consider implementing an SQL metadata backend (e.g., PostgreSQL, MySQL) to replace ETCD for better stability under intensive workloads.
The RisingWave team is working on implementing an SQL metadata backend to address these issues in the upcoming release 1.8.
