libeblob is a low-level IO library which stores data in huge blob files appending records one after another. * fast append-only updates which do not require disk seeks * compact index to populate lookup information from disk * multi-threaded index reading during startup * 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 blob-file-as-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 * usually 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 * run-time sync support - dedicated thread runs fsync on all files on timed base * in-memory index lives in memory mapped file
