Doug Cutting commented on AVRO-1229:
------------------------------------
> Is the expectation that all sequences of calls to write/readBoolean() will be
> followed by a call to write/readLength()?
No, rather those are the only other calls that are ever intermixed with
read/writeBoolean(). Column buffers contain either entirely instances of the
same scalar type (boolean in this case) or, in the case of an array of scalars,
they have length-prefixed sequences of scalars.
The API could be improved to enforce this. We should perhaps instead have
something like OutputBuffer<T> with just two methods, write(T) and
writeLength(int), then a factory that returns different implementations for
different types. Regardless, lengths are the only type that's ever intermixed
with other types.

> Trevni currently provides no native support for Boolean types. As part of the
> Avro support, Booleans should be available. The Impala code recognizes this
