ASF GitHub Bot commented on BEAM-360: ------------------------------------- GitHub user chamikaramj opened a pull request: https://github.com/apache/incubator-beam/pull/507 [BEAM-360] Implements a framework for developing Python SDK sources for new file types Module 'filebasedsource' provides a framework for creating sources for new file types. This framework implements several features common to many sources based on files. Additionally, module 'avroio' contains a new source, 'AvroSource', that is implemented using the framework described above. 'AvroSource' is a source for reading Avro files. Adds many unit tests for 'filebasedsource' and 'avroio' modules.

This framework can include > following features that are common to sources based on files. > (1) glob expansion > (2) support for new file-systems > (3) dynamic work rebalancing based on byte offsets > (4) support for reading compressed files. > Java SDK has a similar framework and it's available at - > https://github.com/apache/incubator-beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/FileBasedSource.java -- This message was sent by Atlassian JIRA (v6.3.4#6332)
