There are no plans that I know of currently, although the topic came up two times in separate conversations last night at the SF Hadoop MeetUp.
I think an ability to extract a subset of a schema from a larger one and read/write/transform data accordingly makes a lot of sense. Currently, the Avro spec allows for schema resolution which is sort of a degenerate schema extraction/transformation at the record level without the ability to address or extract nested elements. An addition to the spec for describing other schema extractions may be useful. Further discussion should probably be in a JIRA ticket or at least on the dev list. -Scott On 1/10/12 1:02 PM, "Jason Rutherglen" <[email protected]> wrote: >Are there plans for (or is there already) an AVRO Path implementation >(like XPath, or JSON Path). > >Thanks!
