---------------------------------------
Summary: Create ECInputStream wrapper to choose between
reconstruction and normal reads.
Key: HDDS-6010
URL: https://issues.apache.org/jira/browse/HDDS-6010
Project: Apache Ozone
Issue Type: Sub-task
Components: Ozone Client
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
When all data locations are available, the most efficient reader is
ECBlockInputStream. It also uses less memory as it does not need to buffer the
full stripe. When some data locations are missing, we need to use
ECBlockReconstructedStripeInputStream and ECBlockReconstructedInputStream
together. There needs to be a wrapper class which creates and uses the correct
underlying stream depending on data location availability.
