Returns the resource-based policy document attached to the resource, which can be a table or stream, in JSON format.
GetResourcePolicy follows an eventually consistent model. The following list describes the outcomes
when you issue the GetResourcePolicy request immediately after issuing another
request:
If you issue a GetResourcePolicy request immediately after a PutResourcePolicy
request, DynamoDB might return a PolicyNotFoundException.
If you issue a GetResourcePolicyrequest immediately after a DeleteResourcePolicy
request, DynamoDB might return the policy that was present before the deletion request.
If you issue a GetResourcePolicy request immediately after a CreateTable
request, which includes a resource-based policy, DynamoDB might return a ResourceNotFoundException
or a PolicyNotFoundException.
Because GetResourcePolicy uses an eventually consistent query, the metadata
for your policy or table might not be available at that moment. Wait for a few seconds,
and then retry the GetResourcePolicy request.
After a GetResourcePolicy request returns a policy created using the PutResourcePolicy
request, the policy will be applied in the authorization of requests to the resource.
Because this process is eventually consistent, it will take some time to apply the
policy to all requests to a resource. Policies that you attach while creating a table
using the CreateTable request will always be applied to all requests for that
table.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetResourcePolicy and EndGetResourcePolicy.

| Exception | Condition |
|---|---|
| InternalServerErrorException | An error occurred on the server side. |
| PolicyNotFoundException | The operation tried to access a nonexistent resource-based policy. If you specified an ExpectedRevisionId, it's possible that a policy is present for the resource but its revision ID didn't match the expected value. |
| ResourceNotFoundException | The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE. |
