Examples with InMemoryScope io.pravega.controller.store.InMemoryScope used on opensource projects

Example 1 with InMemoryScope

use of io.pravega.controller.store.InMemoryScope in project pravega by pravega.

the class InMemoryStreamMetadataStore method createScope.

// endregion
@Override
@Synchronized
public CompletableFuture<CreateScopeStatus> createScope(final String scopeName, OperationContext ctx, Executor executor) {
    OperationContext context = getOperationContext(ctx);
    if (!scopes.containsKey(scopeName)) {

        return scope.createScope(context).thenApply(x -> {
            scopes.put(scopeName, scope);
            orderedScopes.put(scopeName, position.incrementAndGet());
            return CreateScopeStatus.newBuilder().setStatus(CreateScopeStatus.Status.SUCCESS).build();
        });
    } else {
        return CompletableFuture.completedFuture(CreateScopeStatus.newBuilder().setStatus(CreateScopeStatus.Status.SCOPE_EXISTS).build());
    }
}

Example 2 with InMemoryScope

use of io.pravega.controller.store.InMemoryScope in project pravega by pravega.
