if you want to temporarily store haskell data in a file – do you have a special way to get it done efficiently?
In an offline, standalone app, I am continuously reusing data volumes of about 200MB, representing Map like tables of a rather simple structure,
key: (Int,Int,Int) value: [((Int,Int),LinkId)]
which take quite a good deal of time to produce.
Is there a recommendation about how to 'park' such data tables most efficiently in files – any format acceptable, quick loading time is the most desirable thing.
Use cereal [1], usually it's fast and easy enough. If you need to be able to access your files for a long time, consider using safecopy [2] (which internally uses cereal as well). [1] http://hackage.haskell.org/package/cereal [2] http://hackage.haskell.org/package/safecopy HTH, -- Felipe.
