Instance Method Details

#do_minify_lua ⇒ Object

Defaults to false.

If true, all Lua is minified conservatively to save bandwidth before any other logic or evaluation.

  @do_minify_lua = [true,'true'].include?(do_minify_lua)
end

#do_preload ⇒ Object

Defaults to false.

If true, shas are preloaded for each Redis connection (which make safe to use EVALSHA even in pipelines).

  @do_preload = [true,'true'].include?(do_preload)
end

#max_tiny_lua ⇒ Object

Scripts shorter than max_tiny_lua are always EVALed.

We skip all logic regarding EVALSHA, extra round-trips for SCRIPT LOAD, etc.

Defaults to 512. Integers and Strings which convert to Integers OK.

  @max_tiny_lua = max_tiny_lua.to_i
end

#preload_cache_size ⇒ Object

The cache of shas which have been preloaded is not allowed to grow larger than this value.

Defaults to 1000.

Prefixed onto all metrics.

  end

#statsd ⇒ Object

Defaults to nil. If non-nil, lots of stats will be tracked via statsd.increment and statsd.timing.
