I have several CGI scripts that I would like coordinate via a
"First In / First Out" style buffer. That is, some processes
are adding work units, and some take the oldest and
start work on them.
What is the right way to do this?
I suppose I could use an SQL server or SQlite ,
but that seems very complex for just a FIFO.
Given how easy it is to use something like SqlLite from
Python I don't think its an unreasonable approach and
it avoids or eases some of the hidden complexities
around using simple files (such as locking issues).
But a lot will depend on transaction volumes etc. If
you never, or rarely, have concurrent accesses then using
a text file might work. Or you could do it all in memory
via a long running process and a queue. But if volumes
are (or could become) high or bursty I'd go for the SQL route.
