Proposals. Custom query slot management, named instances and read-only databases

Hi everyone! Our current project, based on BaseX, was failed on launch, because we have any practice with optimization for NoSQL databases and take the bottleneck with write locks, but we take the unbelievable experience with BaseX. Today I know, how to get the maximum from this DB 1. Custom query slot management. It would be useful, if query command can take the number of taken slot. From code side I know, that some type of requests is very simple, very fast, and DB can return rapidly the results back. And this type of requests may be sticked to some query slots permanently. From other side, heavy xQuery code may be managed automatically by BaseX 2. Named instances We need to start multiple BaseX servers to utilize more then one CPU core. It would be useful to set up the name for each instance by personal .basex config 3. Access mode Next proposal is simple. Allow to manage the type of access (read or write only, both) to DB for list of named instances. This proposal may help with the next architecture: many servers with one DBPATH. Server1 Server2 Server3 | | | -------------------------------- | | | | DB1 DB2 DB3 DB4 DB1 permissions Read: Server1, Server3 Write: Server2 DB2, DB3, DB4 permissions Read: Server1, Server2 Write: Server2 This may protect from DB corrupts. Is it interesting concept?
