-------------------------------------
Summary: MemoryRecords should have slice API
Key: KAFKA-18855
URL: https://issues.apache.org/jira/browse/KAFKA-18855
Project: Kafka
Issue Type: Sub-task
Reporter: Apoorv Mittal
Assignee: Apoorv Mittal
Currently FileRecords have a capability to slice records, however MemoryRecords
don't have any. The slice API in MemoryRecords is needed to limit the
bytes/records being sent to client from broker during `share fetch`. There can
be a subset of records acquired by share fetch for the MemoryRecords batch
hence MemoryRecords should be sliced to only send the batches which are
acquired. If not sliced, then there can be unnecessary bytes transfer from the
broker.
