Leif Hedstrom created TS-3541:
---------------------------------
Summary: Eliminate interrim cache
Key: TS-3541
URL: https://issues.apache.org/jira/browse/TS-3541
Project: Traffic Server
Issue Type: Improvement
Components: Cache
Reporter: Leif Hedstrom
This feature is poorly supported, and causes grief for cache development due to
how it #ifdef’s with the system. There are plans for a new system that would
make the concept of cache hierarchies generic. In the mean time, the suggestion
is that if you need this, you use one of
1) Assigning content to volumes and disks via our existing configs.
2) Use Linux’s bcache feature, which comes with Linux 3.10 or later. I
suspect e.g. ZFS has something similar.
3) Use a third party system to implement the hybrid device (e.g. flash
cache or EnhanceIO.
