Dicer auto-sharder: Infrastructure for building sharded services.

Dicer is a foundational infrastructure system for building sharded services. By colocating in-memory state with the computation that operates on it, Dicer enables applications to achieve low latency, high availability, and cost efficiency at scale. It is widely used across Databricks, where it has driven substantial reliability and performance improvements in production systems.

Gearman provides a generic application framework to farm out work to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions between languages. It can be used in a variety of applications, from high-availability web sites to the transport of database replication events. In other words, it is the nervous system for how distributed processing communicates.
