Yu Li created FLINK-13803: ----------------------------- Summary: Introduce SpillableHeapKeyedStateBackend and all necessities Key: FLINK-13803 URL: https://issues.apache.org/jira/browse/FLINK-13803 Project: Flink Issue Type: Sub-task Reporter: Yu Li
This JIRA aims at introducing a new {{SpillableHeapKeyedStateBackend}} which will reuse most code of the {{HeapKeyedStateBackend}} (probably the only difference is the spill-able one will register a {{HybridStateTable}}), and allow using it in {{FsStateBackend}} and {{MemoryStateBackend}} (only as an option, by default still {{HeapKeyedStateBackend}}) through configuration. The related necessities include but are not limited to: * A relative backend builder class * Relative restore operation classes * Necessary configurations for using spill-able backend This should be the last JIRA after which the spill-able heap backend feature will become runnable regardless of the stability and performance. -- This message was sent by Atlassian Jira (v8.3.2#803003)
