If you try this in normal OCaml code, you'll find that the machine quickly descends into thrashing as the garbage collector repeatedly iterates over swapped memory structures. This module lets you break that limitation. Of course the module doesn't work by magic :-) If your program tries to access these large structures, they still need to be swapped back in, but it is suitable for large, sparsely accessed structures. Secondly, this module allows you to share those structures between processes. In this mode, the structures are backed by a disk file, and any process that has read/write access that disk file can map that file in and see the structures. (more here: http://merjis.com/_file/ancient-readme.txt ) ---------------------------------------------------------------------- Differences in this release: Previously a hard-coded limit of 1024 objects could be stored in one backing file. This limit has now been removed. ---------------------------------------------------------------------- Download: http://merjis.com/developers/ancient ====================================================================== Weblogs 2.1 Weblogs is an OCaml module for importing weblogs from Apache or IIS web servers. In this major release we have modified the API to use arrays of structures instead of lists for efficiency. We have added support for the Ancient module, so that absolutely huge logfiles can now be loaded into memory and analysed. To give you an idea of how large: we have analysed 38 GB of logfiles from one customer on a 64-bit desktop machine with just 2 GB of physical RAM. ---------------------------------------------------------------------- Download: http://merjis.com/developers/weblogs ====================================================================== Both modules are released under LGPL + OCaml linking exception, to make them compatible with the OCaml library and maximise use even in commercial applications.
