From http://www.ioremap.net/projects/libeblob: libeblob is an append-only low-level IO library, which saves data in blob files. Following features are already supported: * fast append-only updates which do not require disk seeks * compact index to populate lookup information from disk * multi-threaded index reading during starеup * O(1) data location lookup time * ability to lock in-memory lookup index (hash table) to eliminate memory swap * readahead games with data and index blobs for maximum performance * multiple blob files support (tested with single blob file on block device too) * optional sha256 on-disk checksumming * 2-stage write: prepare (which reserves the space) and commit (which calculates checksum and update in-memory and on-disk indexes). One can (re)write data using pwrite() in between without locks * usuall 1-stage write interface * flexible configuration of hash table size, flags, alignment * defragmentation tool: entries to be deleted are only marked as removed, eblob_check will iterate over specified blob files and actually remove those blocks * off-line blob consistency checker: eblob_check can verify checksums for all records which have them enabled * run-time sync support - dedicated thread runs fsync in background on all files on timed base * Google's Snappy compression support elliptics depends on this
