------------------------------------
Summary: Track explicit lengths of WALs for more accurate reporting
Key: ACCUMULO-2835
URL: https://issues.apache.org/jira/browse/ACCUMULO-2835
Project: Accumulo
Issue Type: Improvement
Components: replication
Reporter: Josh Elser
Assignee: Josh Elser
Priority: Minor
Presently, during the normal ingest path, the length of each WAL isn't
explicitly tracked. In practice, it isn't necessary because we can read until
the end of the file (EOFException) and track progress only from the beginning.
This makes the bookkeeping easier, but it's then hard to assert intra-file
progress for replication. The only accurate metric that can be made is the
number of files needing replication, while the size actual amount of data that
needs to be sent over the wire is unknown without reading the file to get the
length in number of records.
