Doc Type: Enhancement
Doc Text:
.Asynchronous Garbage Collection An asynchronous mechanism for executing the Ceph Object Gateway garbage collection using the `librados` APIs has been introduced. The original garbage collection mechanism serialized all processing, and lagged behind applications in specific workloads. Garbage collection performance has been significantly improved, and can be tuned to specific site requirements.

Description Matt Benjamin (redhat) 2018-02-23 21:14:50 UTC
Description of problem:
RGW GC (i.e., reclamation of space from deleted objects) is serial and happens in a single thread.  Due to this, space reclamation can be significantly delayed in some workloads.  Implement an efficient mechanism to permit tunable GC effort to match workload requirements.

How reproducible:
100%
