The attached patch (0.9.21 but will apply to other versions with modification) allows the user to pass a batch size to be used instead of the default value of 100.

[Issue 10024] New: MDB_PREVSNAPSHOT broken
by openldap-its＠openldap.org 09 Dec '24

https://bugs.openldap.org/show_bug.cgi?id=10024 Issue ID: 10024 Summary: MDB_PREVSNAPSHOT broken Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: markus(a)objectbox.io Target Milestone: --- It seems that the patch #9496 had a negative side effect on MDB_PREVSNAPSHOT. In certain cases, when opening the DB using MDB_PREVSNAPSHOT, the previous (2nd latest) commit is not selected. Instead, reads show that the latest commit was selected voiding the effect of MDB_PREVSNAPSHOT. I observed this in our test cases a while back. Today, I was finally able to reproduce it and debug into it. When creating the transaction to read the data, I debugged into mdb_txn_renew0. Here, ti (MDB_txninfo; env->me_txns) was non-NULL. However, ti->mti_txnid was 0 (!) and thus txn->mt_txnid was set to 0. That's the reason for always selecting the first (index 0) meta page inside mdb_txn_renew0: meta = env->me_metas[txn->mt_txnid & 1]; This line occurs twice (once for read txn and once for write txn; it affects both txn types). Thus, the chances of MDB_PREVSNAPSHOT selecting the correct meta page is 50-50. It's only correct if the first meta page (index 0) is the older one. I believe that this is related to #9496 because the patch, that was provided there, removed the initialization of "env->me_txns->mti_txnid" in mdb_env_open2. This would explain why txn->mt_txnid inside mdb_txn_renew0 was set to 0. I can confirm that adding back the following two lines back in fixes MDB_PREVSNAPSHOT: if (env->me_txns) env->me_txns->mti_txnid = meta.mm_txnid; The said patch including the removal of these two lines was applied in the commit(s) "ITS#9496 fix mdb_env_open bug from #8704" (Howard Chu on 09.04.21). I hope this information is useful to find a suitable fix. Please let me know if you have questions. Also, I'd be happy to help confirming a potential fix with our test suite. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10274] New: Replication issue on MMR configuration

We use a load balancer (VIP) to poll all of our servers equally. (but it is possible to do performance tests directly on each of the directories) With our current infrastructure we're able to perform approximately 300 MOD/BIND/s. Beyond that, we start to generate delays and can randomly come across one issue. However, when we run performance tests that exceed our write capacity, our replication between servers can randomly create an incident with directories being unable to catch up with their replication delay. The directories update their contextCSNs, but extremely slowly (like freezing). From then on, it's impossible for the directories to catch again. (even with no incoming traffic) A restart of the instance is required to perform a full refresh and solve the incident. We have enabled synchronization logs and have no error or refresh logs to indicate a problem ( we can provide you with logs if necessary). We suspect a write collision or a replication conflict but this is never write in our sync logs. We've run a lot of tests. For example, when we run a performance test on a single live server, we don't reproduce the problem. Anothers examples: if we define different accounts ranges for each server with SALMD, we don't reproduce the problem either. If we use only one account for the range, we don't reproduce the problem either. ______________________________________________________________________ I have add some screenshots on attachement to show you the issue and all the explanations. ______________________________________________________________________ *Symptoms :* One or more directories can no longer be replicated normally after performance testing ends. No apparent error logs. Need a restart of instances to solve the problem. *How to reproduce the problem:* Have at least two servers in MMR mode Set LastBind to TRUE Perform a SLAMD shot from a LoadBalancer in bandwidth mode OR start multiple SLAMD test on same time for each server with the same account range. Exceed the maximum write capacity of the servers. *SLAMD configuration :* authrate.sh --hostname ${HOSTNAME} --port ${PORTSSL} \ --useSSL --trustStorePath ${CACERTJKS} \ --trustStorePassword ${CACERTJKSPW} --bindDN "${BINDDN}" \ --bindPassword ${BINDPW} --baseDN "${BASEDN}" \ --filter "(uid=[${RANGE}])" --credentials ${USERPW} \ --warmUpIntervals ${WARMUP} \ --numThreads ${NTHREADS} ${ARGS} -- You are receiving this mail because: You are on the CC list for the issue.
