From e404e9b81f18c0a36a5c67ebf041ac0a00ca2eb1 Mon Sep 17 00:00:00 2001 From: shishir gowda Date: Tue, 7 Aug 2012 12:55:31 +0530 Subject: cluster/dht: Optimize readdirp calls in DHT Bring in option which is supported by posix xlator to filter out directory's entries from being returned. DHT would now request non-first subvols to filter out directory entries. dht xlator-option readdir-optimize will enable this optimization Change-Id: I35224bc81c9657f54f952efac02790276c35ded5 BUG: 838199 Signed-off-by: shishir gowda Reviewed-on: http://review.gluster.com/3772 Tested-by: Gluster Build System Reviewed-by: Anand Avati --- xlators/cluster/dht/src/dht.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'xlators/cluster/dht/src/dht.c') diff --git a/xlators/cluster/dht/src/dht.c b/xlators/cluster/dht/src/dht.c index 6b156c1d354..a802d895d03 100644 --- a/xlators/cluster/dht/src/dht.c +++ b/xlators/cluster/dht/src/dht.c @@ -329,6 +329,8 @@ reconfigure (xlator_t *this, dict_t *options) GF_OPTION_RECONF ("directory-layout-spread", conf->dir_spread_cnt, options, uint32, out); + GF_OPTION_RECONF ("readdir-optimize", conf->readdir_optimize, options, + bool, out); if (conf->defrag) { GF_OPTION_RECONF ("rebalance-stats", conf->defrag->stats, options, bool, out); @@ -435,6 +437,8 @@ init (xlator_t *this) GF_OPTION_INIT ("assert-no-child-down", conf->assert_no_child_down, bool, err); + GF_OPTION_INIT ("readdir-optimize", conf->readdir_optimize, bool, err); + if (defrag) { GF_OPTION_INIT ("rebalance-stats", defrag->stats, bool, err); } @@ -603,6 +607,10 @@ struct volume_options options[] = { .type = GF_OPTION_TYPE_BOOL, .default_value = "off", }, + { .key = {"readdir-optimize"}, + .type = GF_OPTION_TYPE_BOOL, + .default_value = "off", + }, { .key = {NULL} }, }; -- cgit
