---------------------------------------
Summary: InterProcessSemaphoreV2::getData to check against data
changes on the semaphore
Key: CURATOR-598
URL: https://issues.apache.org/jira/browse/CURATOR-598
Project: Apache Curator
Issue Type: New Feature
Components: Recipes
Affects Versions: 5.1.0
Reporter: Francesco Nigro
InterProcessSemaphoreV2 allows holders to set data on the acquired lease:
exposing an Optional<byte[]> getData would allow an observer to check against
mutex state change despite not being the lock owner (assuming owner has used
setData prior a mutex acquisition).
This can be used to enforce the order of mutex acquisition or just check
owner's identity and/or presence (assuming owner setData prior a mutex
acquisition).
