Package io.deephaven.kv

Class DHContext

java.lang.Object

io.deephaven.kv.KeyPathContextBase

io.deephaven.kv.meta.AtomicDirectoryContext

io.deephaven.kv.DHContext

All Implemented Interfaces:

Context, KeyPathContext

@Module
public class DHContext
extends AtomicDirectoryContext

A KeyPath model around Deephaven-related data.

The /system entry is for system-related data

The /config entry is for configuration-related data

The /data entry is for data-related data

DHContext is the lowest level atomic directory - that is, AtomicDirectoryContext.isLowestLevelAtomicDirectory() is true. It is the widest level of atomicity that we are presenting for KV transactions.
