Eugene Kirpichov created BEAM-2640: -------------------------------------- Summary: Introduce Create.ofProvider(ValueProvider) Key: BEAM-2640 URL: https://issues.apache.org/jira/browse/BEAM-2640 Project: Beam Issue Type: Bug Components: sdk-java-core Reporter: Eugene Kirpichov Assignee: Eugene Kirpichov
When you have a ValueProvider<T> that may or may not be accessible at construction time, a common task is to wrap it into a single-element PCollection<T>. This is especially common when migrating an IO connector that used something like Create.of(query) followed by a ParDo, to having query be a ValueProvider. Currently this is done in an icky way (e.g. https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/datastore/DatastoreV1.java#L615) We should have a convenience helper for that. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
