vulcan generates test keys for Redis.
vulcan is just a single C file. To use, run:
make
Running make in the vulcan/ directory will produce an executable called vulcan.
vulcan expects you to have
hiredis available for linking. (You can
brew install hiredis on OS X, do a source install, or just use your standard
distro packaging.) vulcan also expects pthreads.
Usage is straight-forward:
./vulcan [number of keys] [string|list|set|zset] -h [host] -p [port]
The first argument is the number of keys you wish to generate. vulcan
restricts this only to whatever LONG_MAX is on your system,
although I'd advise you use fewer keys than that.
The second argument is one of string, list, set, or
zset. This is the Redis datatype you wish to generate.
The other options are not required. If you don't pass in host or port
arguments, vulcan will use defaults of 127.0.0.1 and port 6390
(note that, for safety, that port number is not the standard
Redis port of 6379). You do need to pass in both host and port —
vulcan won't assume port 6500 is also localhost. You need both.
Otherwise it'll get mad.
vulcan uses 40 threads to speed up the key generation. On a basic laptop, vulcan can generate and set 100,000 keys in about 600 milliseconds (for any datatype).
vulcan will also output some timing data on stderr when run.
$ ./vulcan 100000 string -h localhost -p 6391
[vulcan] Using hostname localhost and port 6391
[vulcan] set 100000 strings in 623.819000 milliseconds
./vulcan 100000 set -h localhost -p 6391
[vulcan] Using hostname localhost and port 6391
[vulcan] set 100000 sets in 647.544000 milliseconds
$ ./vulcan 10000 zset
