------------------------------------
Summary: Enhance concurrency in DatasetLifecycleManager by
replacing the global lock with resource-specific locks where applicable.
Key: ASTERIXDB-3574
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3574
Project: Apache AsterixDB
Issue Type: Bug
Components: STO - Storage
Affects Versions: 0.9.10
Reporter: Ritik Raj
Fix For: 0.9.10
Currently, all dataset and index metadata operations (create, register, open,
close, and unregister) in DatasetLifecycleManager are synchronized using a
global lock. This limits concurrency.
To improve performance, the global lock can be *downgraded* to a
resource-specific lock when operating on individual datasets or indexes. This
will allow more concurrency while maintaining correctness.
