Interface DistributedConfiguration

All Superinterfaces:

BeanInfo, Cloneable, Closeable, Configuration, OpenJPAConfiguration, Serializable

All Known Subinterfaces:

DistributedJDBCConfiguration

All Known Implementing Classes:

DistributedJDBCConfigurationImpl

public interface DistributedConfiguration
extends OpenJPAConfiguration

A configuration for multiple data stores, each referred as slice. This configuration allows each underlying slice be configured with its own specific configuration properties such as JDBC Driver or connection user/password etc.
This configuration also extends by several policy plugins. A policy plugin is an user implementation of a specific policy interface. A policy implementation is invoked by Slice runtime.
Slice recognizes following policies

Distribution Policy governs how new instances be distributed among the slices.

Replication Policy maintains the same instance in multiple slices.

Query Target Policy narrows the slices for a query execution.

Finder Target Policy narrows the slices for primary key based lookup

Method Detail

getActiveSliceNames

List<String> getActiveSliceNames()

Gets the active slice identifiers. This list is determined by the configuration properties either by explicit listing in openjpa.slice.Names property or by scanning openjpa.slice.*.* properties.
The ordering of the slice identifiers is determined when they are specified explicitly in openjpa.slice.Names property or ordered alphabetically when found by scanning the properties.
This list always returns the identifiers that are active, slices that can not be connected to are not included in this list.

getAvailableSliceNames

List<String> getAvailableSliceNames()
