increase cache partition size to avoid write-aggregation seeks
--------------------------------------------------------------
Key: TS-46
URL: https://issues.apache.org/jira/browse/TS-46
Project: Traffic Server
Issue Type: Improvement
Components: Cache
Environment: all
Reporter: John Plevyak
Currently cache partitions are 8GB. Because each has a write pointer, this
means on a decent size
disk there are a hundred or more write pointers which means a lot of seeking
for writes
(which really should be aggregated). The proposal is to make it possible to
have large partitions
(up to .5 PB) by increasing the side of the cache directory entry from 8 to 10
bytes and using the
additional bits for the offset.
