> We should suggest the users to always enable just one table service for multiple jobs.
> 1. Cleaning: concurrent cleaning is allowed, but there is case concurrent execution from multiple jobs happen, which result in duplicate cleam commit metadata files.(This is behavior for both 0.x and 1.x)
> 2. Compaction: concurrent scheduling is supported because we have completion file filtering for the target logs, cocurrent execution may be problematic
> 3. Clustering: No concurrency is supported.
