As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code,...

    meta-treedb

    on-disk memory library using meta-data

    ...If you follow the tests/examples, you too can store dictionaries, trees, lists or whatever you can think of in disk-based memory, just an open() and mmap() away. Meta-treedb comes with an AVL tree, doubly-linked-list and variable-entry-sized-array implementations for you to use in your data structures. So, what distinguishes meta-treedb from treedb? * "class" interfaces for treedb collections These are vtables (virtual function tables) that implement the interface. * faster compiles - only the "class" interfaces are visible to client code This is at the expense of a small performance hit. * the ability to use implementations that were developed after client code was compiled.

    Occursions

    Fast customizable time series web database for big data like log files

    ...Occursions asynchronously tails log files and indexes the individual lines in each log file as each line is written to disk so you don't even have to wait for a second after an event happens to search for it. Occursions uses custom disk backed data structures to create and search its indexes so it is very efficient at using CPU, memory and disk. You can extend Occursions with shared libraries to support your own file formats, even binary file formats!
