OlegDB

Alternate title: "How far can we push a mayonnaise metaphor?"

$ pgrep olegdb | xargs kill
olegdb: No.

OlegDB is a single-threaded, non-concurrent, transactionless NoSQL database written by bitter SQL-lovers in a futile attempt to hop on the schemaless trend before everyone realizes it was a bad move. It is primarily a C library with an Erlang frontend for communication.

Dependencies

• A healthy fear of the end
• Erlang

Installation

OlegDB consists of a server written in Erlang and a C library for all of the heavy lifting. Binaries are in build/bin/ and the library is in build/lib/. Beam files are also thrown in build/bin/.

Currently builds are tested against gcc and clang.

# Building everything:
make
# Just the erlang beam files:
make server
# Just the C library:
make liboleg
# Install
sudo make install

To run tests:

./run_tests.sh

To run the erlang server:

olegdb <db_location>

You can optionally specify a port, host or both. But not just a host.

olegdb <db_location> [[host] port]

curl2sudo® install script coming soon.
