Summary: Ozone: Add client Block cache for SCM
Key: HDFS-12900
URL: https://issues.apache.org/jira/browse/HDFS-12900
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
Fix For: HDFS-7240
SCM blocks are currently allocated via the SCM block client rpc. This would
involve multiple rpc requests for block allocation requests. This can be
optimized by having a block cache on the client.
This cache can be used to pre-allocate multiple blocks. This layer can also be
optimized to handle block frees as well by keeping the freed blocks in the
cache and using them for further allocations.
