From 4d118cb5ee99b8401d70678fc3b3576ad938999d Mon Sep 17 00:00:00 2001 From: Joseph Fernandes Date: Thu, 9 Apr 2015 15:07:54 +0530 Subject: ctr/libgfdb: Performance enhancer for unlink/create/rename/link fops 1) ctr_link_consistency option for ctr xaltor is provided so that the user can choose to switch it on or off. /* For link consistency we do a double update i.e mark the link * during the wind and during the unwind we update/delete the link. * This has a performance hit. We give a choice here whether we need * link consistency to be spoton or not using link_consistency flag. * This will have only one link update */ 2) In delete the wind time recording is moved to unwind path. /* Special performance case: * Updating wind time in unwind for delete. This is done here * as in the wind path we will not know whether its the last * link or not. For a last link there is not use to update any * wind or unwind time!*/ Change-Id: I209472fb816f939db4a868b97ba053b028f17ea6 BUG: 1217786 Signed-off-by: Joseph Fernandes Reviewed-on: http://review.gluster.org/10170 Reviewed-by: Dan Lambright Tested-by: Gluster Build System --- xlators/mgmt/glusterd/src/glusterd-volume-set.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'xlators/mgmt/glusterd/src/glusterd-volume-set.c') diff --git a/xlators/mgmt/glusterd/src/glusterd-volume-set.c b/xlators/mgmt/glusterd/src/glusterd-volume-set.c index 17f34e6f86d..c57840f0fde 100644 --- a/xlators/mgmt/glusterd/src/glusterd-volume-set.c +++ b/xlators/mgmt/glusterd/src/glusterd-volume-set.c @@ -1730,8 +1730,13 @@ struct volopt_map_entry glusterd_volopt_map[] = { .option = "record-counters", .op_version = GD_OP_VERSION_3_7_0 }, + { .key = "features.ctr_link_consistency", + .voltype = "features/changetimerecorder", + .value = "off", + .option = "ctr_link_consistency", + .op_version = GD_OP_VERSION_3_7_0 + }, #endif /* USE_GFDB */ - { .key = "locks.trace", .voltype = "features/locks", .type = NO_DOC, -- cgit
