fsdb | file system data base .

fsdb is a Ruby library. fsdb has no vulnerabilities and it has low support. However fsdb has 2 bugs. You can download it from GitHub.

FSDB is a file system data base. FSDB provides a thread-safe, process-safe Database class which uses the native file system as its back end and allows multiple file formats and serialization methods. Users access objects in terms of their paths relative to the base directory of the database. It's very light weight (the per-process state of a Database, excluding cached data, is essentially just a path string, and code size is very small, under 1K lines, all ruby). FSDB stores data at nodes in the file system. The format can vary depending on type. For example, the default file type can be read into your program as a string, but files with the .obj suffix could be read using marshal, and files with the .yaml suffix as yaml. FSDB can easily be extended to recognize other formats, both binary and text. FSDB treats directories as collections and provides directory iterator methods. Files are the atoms of transactions: each file is saved and restored as a whole. References between objects stored in different files can be persisted as path strings. FSDB has been tested on a variety of platforms and ruby versions, and is not known to have any problems. (On WindowsME/98/95, multiple processes can access a database unsafely, because flock() is not available on the platform.) See the Testing section for details. FSDB does not yet have any indexing or querying mechanisms, and is probably missing many other useful database features, so it is not a general replacement for RDBs or OODBs. However, if you are looking for a lightweight, concurrent object store with reasonable performance and better granularity than PStore, in pure Ruby, with a Ruby license, take a look at FSDB. Also, if you are looking for an easy way of making an existing file tree look like a database, especially if it has heterogeneous file formats, FSDB might be useful.
