------------------------------------
Summary: Channel.size() is costly, mutually exclusive, and on the
critical path
Key: CASSANDRA-10529
URL: https://issues.apache.org/jira/browse/CASSANDRA-10529
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Benedict
Fix For: 3.0.0 rc2
[~stefania_alborghetti] mentioned this already on another ticket, but I have
lost track of exactly where. While benchmarking it became apparent this was a
noticeable bottleneck for small in-memory workloads with few files, especially
with RF=1. We should probably fix this soon, since it is trivial to do so, and
the call is only to impose an assertion that our requested length is less than
the file size. It isn't possible to safely memoize a value anywhere we can
guarantee to be able to safely refer to it without some refactoring, so I
suggest simply removing the assertion for now.
