Spillable key value storage (integrate with APEXMALHAR-2026) > 2. Upon checkpoint, it saves a snapshot for the entire data set with the checkpointing window id. This should be done incrementally (ManagedState) to avoid wasting space with unchanged data > 3. When recovering, it takes the recovery window id and restores to that snapshot > 4. When a window is committed, all windows with a lower ID should be purged from the store. > 5. It should implement the WindowedStorage and WindowedKeyedStorage interfaces, and because of 2 and 3, we may want to add methods to the WindowedStorage interface so that the implementation of WindowedOperator can notify the storage of checkpointing, recovering and committing of a window. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
