An easy way to read and write records. A record is data wrapped with some metadata that can delimit a single peice of data from a large set.

The current protocol is simple and fairly naive:

[magic-number] [compressed-size] [data]
|<---------- header ---------->|

Overhead per record: 16B (8B + 8B)

Uses the Go port of Google's snappy compression library.

All records are unconditionally compressed. Snappy might add a few additional bytes of overhead.

See test/recordio_test.go for usage.

1. Integrity check: something like SHA-256 on the compressed data.
2. Better examples.
