Abstract
Disclosed herein are system, method, and computer program product embodiments for managing timestamp information in memory systems. In an embodiment, an infrastructure may utilize a controller to manage sparse timestamp blocks. These sparse timestamp blocks may manage timestamp information in a persistent memory structure. Controllermay utilize a transient timestamp accessor to map the timestamp information for faster hash lookups. Controllermay also utilize a garbage collection map as a bitmap to further save processing steps. Controllermay utilize the sparse timestamp blocks, transient timestamp accessor, and garbage collection map to efficiently store timestamp data and to quickly retrieve the stored timestamp data.
