             Summary: [Format] Define Flatbuffers metadata for random-access 
compressed block memory format
                 Key: ARROW-730
                 URL: https://issues.apache.org/jira/browse/ARROW-730
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Format
            Reporter: Wes McKinney


It would be useful to be able to create a compressed buffer stream as a series 
of fixed-size blocks, with metadata written at the footer of the stream, so 
that random access is possible.

{code}
compressed_block[0]
...
compressed_block[N-1]
compression metadata
metadata_size (int32)
{code}
