Maximum length of a job payload?

[aaronpk]

Hi, I recently started using beanstalk, and I couldn't seem to find
the answer to this question in the docs or on this list. What is the
maximum length (if any) of a job? How much data is expected to be
included in the job? I'm considering en-queuing jobs that could
potentially have as much as 10kb of data in them.

Thanks,

Aaron

Maximum job size is reported by the stats command,
documented here:

https://github.com/kr/beanstalkd/blob/v1.4.6/doc/protocol.txt#L566

Admittedly, this document isn't the most obvious place
for beanstalkd users to look.

You can control this value with option -z on the command line.
The default is somewhat arbitrary: 65,535 bytes.

$ beanstalkd -h
Use: beanstalkd [OPTIONS]

Options:
[snip...]
-z BYTES set the maximum job size in bytes (default is 65535)

Thanks. don't know why I didn't think to check the help in the program.

Are there many downsides to allowing larger jobs? 256k or so? Similarly, is there a performance increase by restricting the job length to something smaller like 1k or 512 bytes?

Thanks, Aaron

This option doesn't affect speed at all.

Performance depends only on the actual jobs you put in the queue.
The server doesn't copy a job once it has been read from the network,
but larger jobs still take longer to receive and send.
