Description

This JIRA aims at introducing a HybridStateTable which could combine everything together, like checking the heap usage through HeapAccountingManager and GC status through HeapStatusMonitor to decide whether to spill/load key groups, triggering the spill/load action through SpillLoadManager, and recording all meta data (about which key group is on heap, which is on disk), etc.
