[23:34] <hyc> ok, so far heap profile shows that memory use during refresh is normal
[23:35] <hyc> not wonderful, but normal. mem usage grows because we're recording the present list while receiving entries in the refresh
[23:36] <hyc> I'm seeing for 1.2GB of data about 235MB of presentlist
[23:36] <hyc> which is pretty awful, considering presentlist is just a list of UUIDs
[23:36] <hyc> being stored in an avl tree
[23:37] <hyc> a btree would have been better here, and we could just use an unsorted segmented array
[23:42] <hyc> for the accumulation phase anyway. we need to be able to lookup records during the delete pphase
[00:05] <hyc> this stuff seriously needs a rewrite
[01:13] <hyc> 2.8M records x 16 bytes per uuid so this should be no more than 48MB of overhead
[01:13] <hyc> and instead it's 3-400MB
<hyc> get lmdb incremental backup working
<hyc> I need to publish a spec for PREPARE/2-phase commit in LDAP TXNs and integrate that into lmdb and back-mdb
