Hi all! While the idea of using memcached with ccache is nothing new (*), it seems to be more popular now with more memory being available...
* https://lists.samba.org/archive/ccache/2010q4/000686.html https://lists.samba.org/archive/ccache/2013q2/001120.html Pierre Tardy made a PR (https://github.com/jrosdahl/ccache/pull/30) to replace the filesystem ("fs") cache with memcached altogether. We have gone with a different approach, to use memcached only as a secondary cache - while preserving the primary cache (on the disk). Also added support for big files larger than memcached default (1M), without having to modify the servers - by splitting them up if needed. Manifests are just stored in a single entry in the memcached, while other files are being combined into one entry per cache key (md4-len) The idea is that hitting this secondary cache is still cheaper than doing a compile again, but could be slower than not using the network. The overhead of having each and every ccache invocation call memcached, can be avoided by setting up a local memcached proxy ("moxi") server. There is a public branch available, rebased from a 3.1 version: https://github.com/itensionanders/ccache/tree/memcached It has been (recently) updated to "3.2-maint", but not to "master". Being a work in progress still, it's not ready for merging just yet. But I would like some early feedback, and perhaps some more testing ? More benchmarking needs to be done, and for some different scenarios. /Anders _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
