Unisrv: Universal NoSQL database server

Unisrv is a database server: a microservice that exports local filesystem databases over a network. It is the swiss army knife of db services.

Unisrv can export a gdbm database over HTTP REST, a rocksdb database over JSON-RPC, and more. You can mix and match database type, network protocol interface and authentication methods.

Configuration

See configuration documentation for details.

Logging

Log output is sent to the console (stderr) and Unix syslog service.

Supported database types

The following database types are supported:

• gdbm
• Rocksdb

Supported network protocols

You may export the database via any number of network protocols:

• REST over HTTP
• JSON-RPC over HTTP

HTTP endpoint sharing

Multiple HTTP paths at the same HTTP endpoint are supported; for example

http://127.0.0.1:8989/data/mydata

might export a gdbm database, while the same HTTP endpoint may also export a separate dataset from rocksdb at

http://127.0.0.1:8989/rocks

Dependencies

Building and installing

This uses the standard autotools pattern for building C++ programs:

$ ./autogen.sh
$ CXXFLAGS="-O2 -Wall -g -I/usr/local/include/evhtp" ./configure
$ make			# compile
$ make check		# run tests
$ sudo make install	# install on system
