vulcan ======= **vulcan** generates test keys for Redis. usage ------ 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](https://github.com/redis/hiredis.git) 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. example --------- ``` $ ./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 [vulcan] Using hostname 127.0.0.1 and port 6390 [vulcan] set 10000 zsets in 67.041000 milliseconds ``` ``` $ ./vulcan 10000 string -h localhost -p 6391 [vulcan] Using hostname localhost and port 6391 [vulcan] set 10000 strings in 73.126000 milliseconds ``` license -------- MIT
