Ben Chambers created BEAM-135: --------------------------------- Summary: Utilities for "batching" elements in a DoFn Key: BEAM-135 URL: https://issues.apache.org/jira/browse/BEAM-135 Project: Beam Issue Type: Bug Components: sdk-java-core Reporter: Ben Chambers
We regularly receive questions about how to write a {{DoFn}} that operates on batches of elements. Example answers include: http://stackoverflow.com/questions/35065109/can-datastore-input-in-google-dataflow-pipeline-be-processed-in-a-batch-of-n-ent/35068341#35068341 http://stackoverflow.com/questions/30177812/partition-data-coming-from-csv-so-i-can-process-larger-patches-rather-then-indiv/30178170#30178170 Possible APIs could be to wrap a {{DoFn}} and include a batch size, or to create a utility like {{Filter}}, {{Partition}}, etc. that takes a {{SerializableFunction}} or a {{SimpleFunction}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
