The KV DAL allows applications to use a well-defined and storage engine agnostic HTTP/gRPC key-value data interface that in turn decouples applications from hard to maintain and backwards-incompatible datastore APIs. One namespace in a Key-Value DAL contains as many key-value data as required, it is the equivalent to a table in a database.

Database administrators with appropriate privileges can associate virtual CPUs with resource groups and assign threads to these groups. Then we need to see IF implementing the tuning will work or not. It is possible to do more tuning in the case that ETL is too compromised. Currently, CPU affinity (i.e., Will this work?
