From c41a9d1c3fe4002bdf8849c4e8ae7c2e10841c69 Mon Sep 17 00:00:00 2001 From: Anand Avati Date: Sat, 24 Sep 2011 16:14:11 +0530 Subject: md-cache: meta-data caching translator This is a metadata caching translator which is well integrated with glusterfs core framework and leverages some of the recent protocol changes to do a better job at caching. - It uses the attributes returned along callbacks of all calls to update its attribute cache as frequently as possible without issuing calls on its own (i.e, very low overhead) - It caches attributes returned via readdirp into the inode contexts corresponding to those entries (i.e, well integrated) - It caches and updates xattrs and not just inode attributes (i.e, eliminates the need for a separate xattr-prefetch translator) In its current form it has a timeout based consistency model Change-Id: I891f6225c1a4c08bb111e287571d5f6d326dbe97 BUG: 765785 Reviewed-on: http://review.gluster.com/2713 Tested-by: Gluster Build System Reviewed-by: Anand Avati --- xlators/performance/md-cache/Makefile.am | 1 + 1 file changed, 1 insertion(+) create mode 100644 xlators/performance/md-cache/Makefile.am (limited to 'xlators/performance/md-cache/Makefile.am') diff --git a/xlators/performance/md-cache/Makefile.am b/xlators/performance/md-cache/Makefile.am new file mode 100644 index 00000000000..af437a64d6d --- /dev/null +++ b/xlators/performance/md-cache/Makefile.am @@ -0,0 +1 @@ +SUBDIRS = src -- cgit
