Description Deniss Gaplevsky 2012-01-13 12:11:24 UTC

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

Extra space in DESCRIPTION should be removed.

add python bindings when compiled with "python" use flags
remove boost dependence while compiled without "python" use flags
