Hi, does anyone know if it rocksdb is ready for use as omap db on jewel?
According to the release notes of RH Ceph 2.4, "RocksDB is enabled as an option to replace levelDB" and they even have a solution on how to convert the leveldb omap db to rocksdb (https://access.redhat.com/solutions/3210951) which mentions you need at least 10.2.7. However, to be able to use it on upstream ceph 10.2.10, you still need to set the "enable experimental unrecoverable data corrupting features = rocksdb" setting in ceph.conf, and on every "ceph health" or other command you get the warning "the following dangerous and experimental features are enabled: rocksdb". We have a lot of performance issues with due to very large omap db's and would love to find out if switching to rocksdb would help there. Anyone any experience with this (good or bad)? regards, Sam _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
