Hi, I'm looking at the spec for the container file, and have 2 questions:
The map of metadata key/value pairs begins with a long, then a number of string-key/bytes-value pairs. To be consistent with avro maps, should this be followed by a long of 0? The spec doesn't say explicitly, but if the header is described by an avro schema I would suspect yes. Are the longs that describe the file block varint longs? Or 64-bit longs? I assume avro varints. But if so, if you ever wanted to expand the size of block by writing more objects to it, you'd be in trouble because you'd potentially be unable to fit the new size in the varint's location. Also, I looked around the repo for some example container files, but didn't see any. Are there any examples checked in that we can use to examine their layout and test our readers? thanks, Scott
