Package org.apache.drill.exec.cache Description

Distributed cache for syncing state and data between Drillbits. The distributed cache defined in this package can be used to make data available to all of the nodes in a Drill cluster. This is useful in cases where most of the work of a given operation can be separated into independent tasks, but some common information must be available to and mutable by all of the nodes currently involved in the operation.
