How can I interpret the rdb file

[Kashif]

antirez,
I am writing a script that needs to read the dump.rdb file. I have
not been able to figure out how it formatted - I have gone through
rdb.c but because I am not a C programmer, I havent been able to
figure out the solution. How is dump.rdb formatted and encoded?

Thanks

The full format of the .rdb file is a little much to explain in a
quick one-off "how does it work, I don't understand C" thread. My
advice: learn as much C as is necessary to understand the code that
was written ('introduction to C' offers some good links at Google),
and write your decoder while going through the code. While writing
your decoder, also have a small .rdb that you have saved in advance to
test your decoder against.

Also, learning C is worth the time. As long as you know some other
procedural language in advance, C shouldn't be much of a problem.

There is also some perl code out there to read and write .rdb files
(search the archives of this group), but I would still suggest
learning C.

I'm sorry Kashif, but currently the only "specification" for the RDB
file format is the source code itself.
This is not good and should be addressed, I'm adding this to the TODO
list, hoping that some good soul will take the challenge and help us
with that, otherwise I'll try to find the time to do it myself.

Cheers,
Salvatore

Thank you for your responses, when I figure it out I will try to help
with the related documentation.

Hi,

I spent some time documenting the rdb file format - https://github.com/sripathikrishnan/redis-rdb-tools/blob/master/RDB_File_Format.textile, others may find it useful.

The github project also has a python script to parse the rdb file. This script is work in progress. Right now, the script is unable to parse LZF compressed strings. Other than that, it can parse the entire rdb file.
