'a Java port of Twitter's Snowflake thrift service presented as an HTTP-based Dropwizard service'.
an HTTP-based service for generating unique ID numbers at high scale with some simple guarantees. supports returning ID numbers as: JSON and JSONP; Google's Protocol Buffers; Plain text.

At GE, we were more interested in the uncoordinated aspects of Snowflake than its throughput requirements, so HTTP was fine for our needs. We also exposed the core of Snowflake as an embeddable module so it can be directly integrated into our applications. We don't have the guarantees that the Snowflake-Zookeeper integration was providing, but that was also acceptable to us. In places where we really needed high throughput, we leveraged the snowizard-core embeddable module directly.

Odd OSS license, though -- BSDish?
