summary
Deutsche Telekom describes librmb, a library that stores email directly in Ceph RADOS objects on a petabyte-scale proof-of-concept cluster to enable parallel I/O for millions of users and billions of messages. The implementation uses erasure coding, compression, and index/metadata caching with a plugin that maps mailboxes to objects; tests show high raw object throughput but metadata/index latency and single-threaded components slow search and recovery, and recent bugfixes improved stability while metadata performance remains the primary bottleneck.
