--------------------------------------
Summary: Provide ability to create regions from client
Key: GEODE-215
URL: https://issues.apache.org/jira/browse/GEODE-215
Project: Geode
Issue Type: Improvement
Components: core
Reporter: Swapnil Bawaskar
Currently regions on the server are created through gfsh or by declaring them
in cache.xml. The API to create regions on client, creates regions only on the
client which then connects to an existing region on the server with the same
name.
h4. New API
The improvement proposed here is to provide an API from the client to create
regions on the server.
The current client API to create regions is:
{code}
clientCache.createClientRegionFactory(ClientRegionShortcut).create();
{code}
For applications that embed GemFire servers, there is already an API to create
regions on the servers:
{code}
cache.createRegionFactory(RegionShortcut).create();
{code}
The clients should support this API so that it can create regions on the
server. Since this method returns a Region, we should create a
ClientRegionShortcut.PROXY region on the client. If a different region type is
desired on the client, users can first use createClientRegionFactory() to
create the region on the client followed by using createRegionFactory() to
create the region on the server.
h4. Destroy Region
For destroying a region, we already have two APIs on the region destroyRegion()
and localDestroyRegion().
The clients could use destroyRegion() to destroy the region on the server and
use localDestroyRegion() to destroy the region locally.
Currently, destroyRegion() is not distributed to others if the scope of the
region is LOCAL (which is the case of client regions).
Although the proposal here will break backwards compatibility, I feel we should
make this change to make the API more intuitive.
