Support for "map" type?

[sutram]

Is this something that you are planning to add?
Thanks.

[julianpeeters]

Yes, however the timeframe for completion is uncertain. Likely within one or two months. Pull requests welcome.

[sutram]

Ok, no problem. Can you point me to the area of code that I need to look at?

[julianpeeters]

Sure. If you'd like to take a look, I've made a branch with a handful of Map tests and AvroRecord will need to be updated for them to pass.

Avro takes in a ClassDef, reads its set of fields, and emits a ClassDef with new members based on those fields. Specifically, the methods generateNewCtors, generateSchema, generateNewMethods need to know what to generate when they are passed a set of fields that contains a map.

For example, when AvroRecord tries to make zero-arg constructor, it needs a default value for each field, but currently doesn't know what default to use when the field is a Map.

I'm going to start on this feature, so if by chance there has been any progress here, please share any scraps. :)

[sutram]

Unfortunately, I've been extra busy recently so I haven't done much. Sorry.

[julianpeeters]

No worries at all.

Maps are now supported for Scala 2.11, with release version 0.9.0.

Support for Maps in 2.10 will come as well.

This works great! Looking forward to the port to 2.10.

Thanks,
Sutram

[julianpeeters]

Good to hear.

You can try with 2.10 by using release version 0.4.1, should be syncing with maven central in a couple hours.

[sutram]

I verified that the 2.10 version works as well!

[julianpeeters]

OK great, thanks for the report. Happy Avro-ing.
