Cache BufferedRandomAccessFile.length
-------------------------------------
Key: CASSANDRA-950
URL: https://issues.apache.org/jira/browse/CASSANDRA-950
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Johan Oskarsson
Profiling shows that BufferedRandomAccessFile.length is eating up an unexpected
amount of cpu. It believe it is the call through the "native barrier" that is
causing it. We often call the length method via is end of file when reading
data. We can add caching of the file length to avoid this call most times.
