Package com.hazelcast.hotrestart Description

Public API for the Hot Restart store.

A Hot Restart store is used internally by Hazelcast to provide the Hot Restart feature: the ability to restart after a crash or shutdown with its data structures restored to the state before going down.

The Hot Restart Store exposes the following probes:

• hot-restart.<store_name>.valOccupancy: approximate amount of data stored in main chunk files (does not account for data in the active chunk);
• hot-restart.<store_name>.valGarbage: approximate amount of garbage within that data (does not account for garbage in the active chunk);
• hot-restart.<store_name>.tombOccupancy: approximate amount of data stored in tombstone chunk files (does not account for data in the active tombstone chunk);
• hot-restart.<store_name>.tombGarbage: approximate amount of garbage within that data (does not account for garbage in the active tombstone chunk);
• hot-restart.<store_name>.liveValues: the number of live value records in the store;
• hot-restart.<store_name>.liveTombstones: the number of live tombstone records in the store.
