 1 | ## BTable
 2 | 
 3 | A fast, compact binary serialization format for sparse, labeled 2D numeric datasets ('binary tables').
 4 | 
 5 | ### Motivations
 6 | 
 7 | Prior to BTables, we were storing large sparse 2D datasets in dense CSVs, which is highly space- and
 8 | performance-inefficient. We looked into [HDF5](http://www.hdfgroup.org/HDF5/) although found it to be
 9 | overly complex for our use case, and early investigation did not yield compelling gains in performance
10 | or space. Thus BTables was designed to be a simple, fast, and compact format to represent sparse numeric
11 | datasets.
12 | 
13 | A BTable is basically a binary representation of a sparse matrix on disk, and the format is inspired
14 | by the [Compressed Row Storage](http://netlib.org/linalg/html_templates/node91.html) (CRS) format,
15 | saving space by only storing the indices/values of nonzero cells. It is designed in a strictly
16 | row-oriented format for efficient iteration, and is _not_ a library for matrix computation or
17 | linear algebra.
18 | 
19 | Note that BTables are *not* a drop-in replacement for all datasets stored as CSV:
20 | the increases in efficiency is proportional to the sparsity of the dataset.
21 | For a pathological fully-nonzero dataset, the space occupied can be much larger than a CSV!
22 | 
23 | ### Examples
24 | 
25 | ```clj
26 | (require '[clj-btable.core :as btable])
27 | 
28 | (def labels ["login", "view_item", "purchase"])
29 | (def rows [[5.0 3.0 1.0] [2.0 0.0 0.0] [0.0 0.0 0.0]])
30 | (btable/write "out.btable" labels rows)
31 | ; #
32 | 
33 | (btable/labels "out.btable")
34 | ; => ["login", "view_item", "purchase"]
35 | 
36 | (doseq [row (btable/rows "out.btable")]
37 |   ; Process a single row in a lazy sequence of rows
38 |   )
39 | ```
40 | 
41 | Also see [the documentation](http://framed-data.github.io/clj-btable).
42 | 
43 | ### Disk format
44 | 
45 | See [the wiki](https://github.com/framed-data/clj-btable/wiki/Disk-Format) for a detailed description of the representation on disk.
46 | 
47 | 
48 | ### Performance
49 | 
50 | An optimized Java backend using NIO can write a table of 50,000 rows, each with 500 columns (25 million cells) in just under 6 seconds.
51 | The same table can be read/traversed in ~7s.
