(ITS#7667) performance degradation when using MDB_INTEGERKEY
by romange＠gmail.com 18 Aug '13

18 Aug '13

Full_Name: Roman Gershman Version: OS: linux 3.8.0-25-generic URL: Submission from: (NULL) (212.150.97.210) The program writes into mdb database 100 million key,value pairs. All keys are 64bit integers. If we open the new database with mdb_dbi_open(txn, NULL, 0, &dbi); it has excellent performance - writes are done very quickly. However if we open it with "mdb_dbi_open(txn, NULL, MDB_INTEGERKEY, &dbi)" (and this is the only change in the code) its performance quickly deteriorates and after it writes several million items to the clean db the difference in write times becomes 2 orders of magnitude or even more compared to the previous setting. We used the source from git repository git://gitorious.org/mdb/mdb.git at commit id 214e9ed07d566307f22e16d0c1f1f57be9504a3b

This is a bit more extreme though, it terminates all client connections and suspends the slapd listeners while a refresh is running. The solution discussed in this ITS would be preferable. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Re: (ITS#7665) LMDB: Documentation issue or mistake: MDB_NOMETASYNC vs MDB_CREATE

Hi Hallvard, I want to thank you so much for your timely responses. I'm very glad to interact with a so responsible team. Changing MDB_CREATE is clearer, indeed allows separate both sets with a simple mask. Talking about the documentation, I think that should be stressed somewhere that when using named databases, the main one (unnamed) should not be used for regular work without special care and some constraints. Maybe that a remark in mdb_dbi_open would be sufficient. Regards and thanks again. Salvador.

(ITS#7665) LMDB: Documentation issue or mistake: MDB_NOMETASYNC vs MDB_CREATE
by sog＠msg.com.mx 14 Aug '13

Full_Name: Salvador Ortiz Version: OS: URL: Submission from: (NULL) (187.162.45.111) The documentation states that the Environment's flags should not overlap with the Database's ones, but MDB_NOMETASYNC and MDB_CREATE share the same value. There is unused bits in the low word. We are still at time to change MDB_CREATE?
