Anuj Modi updated HADOOP-19613: ------------------------------- Description: Read Buffer Manager used today was introduced way back and has been stable for quite a while. Read Buffer Manager to be introduced as part of https://issues.apache.org/jira/browse/HADOOP-19596 will introduce many changes incrementally over time. While the development goes on and we are able to fully stabilise the optimized version we need the current flow to be functional and undisturbed. This work item is to isolate that from new code by refactoring ReadBufferManager class to have 2 different implementations with same public interfaces: ReadBufferManagerV1 and ReadBufferManagerV2. This will also introduce new configs that can be used to toggle between new and old code. > ABFS: [ReadAheadV2] Refactor ReadBufferManager to isolte new code with the > current working code > ----------------------------------------------------------------------------------------------- > > Key: HADOOP-19613 > URL: https://issues.apache.org/jira/browse/HADOOP-19613 > Project: Hadoop Common > Issue Type: Sub-task > Reporter: Anuj Modi > Assignee: Anuj Modi > Priority: Major > > Read Buffer Manager used today was introduced way back and has been stable > for quite a while. > Read Buffer Manager to be introduced as part of > https://issues.apache.org/jira/browse/HADOOP-19596 will introduce many > changes incrementally over time.
