## Description
This Apache Druid module provides a per-lookup caching mechanism for JDBC data
sources.
The main goal of this cache is to speed up the access to a high latency lookup
sources and to provide a caching isolation for every lookup source.

Dynamic Configuration

+> Static configuration is no longer supported.

The following documents the behavior of the cluster-wide config which is
accessible through the Coordinator.
The configuration is propagated through the concept of "tier" of servers.
A "tier" is defined as a group of services which should receive a set of
lookups.
