lmdb is single-writter-thread
- hyc_symas 12y agoHow is that in any way relevant? All ARIES write-ahead-logger systems are single-writer to their logs too. No matter what kind of BS they sell you about high concurrency with fine-grained locking, it all funnels thru that single bottleneck. The fact is that LMDB's single-writer design is not a concurrency liability in real workloads. http://symas.com/mdb/20141120-BuildStuff-Lightning.pdf http://symas.com/mdb/20141120-BuildStuff-Lightning.pdf http://symas.com/mdb/#bench http://symas.com/mdb/#bench
