Chamikara Jayalath resolved BEAM-2643. -------------------------------------- Resolution: Fixed Fix Version/s: 2.2.0 > Add TextIO and AvroIO read transforms that can read a PCollection of files > -------------------------------------------------------------------------- > > Key: BEAM-2643 > URL: https://issues.apache.org/jira/browse/BEAM-2643 > Project: Beam > Issue Type: New Feature > Components: sdk-py > Reporter: Chamikara Jayalath > Assignee: Chamikara Jayalath > Fix For: 2.2.0 > > > Java SDK now has TextIO.read_all() API that allows reading a massive number > of files by moving from using the BoundedSource API (which may perform > expensive source operations on the control plane) to using ParDo operations. > https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/TextIO.java#L170 > This API should be added for Python SDK as well. > This form of reading files does not support dynamic work rebalancing for now. > But this should not matter much when reading a massive number of relatively > small files. In the future this API can support dynamic work rebalancing > through Splittable DoFn. > cc: [~jkff] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
