zoom-cache: A streamable, seekable, zoomable cache file format

==============================================================

[![Build Status](https://secure.travis-ci.org/kfish/zoom-cache.png)](http://travis-ci.org/kfish/zoom-cache)

These are some of the goals of the zoom-cache format:

Writing

-------

    * can be written to in streaming manner, with no backseeking

Reading

-------

    * can be read in one pass with no backseeking

    * can be seeked on time-wise

    * sections can be extracted

    * can be read at varying zoom levels

Data

----

    * Support multiple data types (float/double, int, bool, char)

    * support multiple aggregation types for zooming (min/max, mean, rms, all/any,

        text summary)

    * Constant or variable bitrates streams

Library

-------

    * Simple stream writing interface

    * Simple stream reading interface

    * Read seek interface

    * Read set-zoom-level interface

Tools

-----

    * Verification

    * Info

Interleaved streams

-------------------

  * Sync points

Index files

-----------

  * A documented way of generating time index files

Exploded form

-------------

  * one file per stream
