Martin Kleppmann commented on SAMZA-481:
----------------------------------------
What do you dislike about it? That it always requires 8 bytes, even for small
numbers?
Avro uses a variable-length encoding that uses one byte for -128 <= x < +128,
two bytes for -16384 <= x < +16384, etc. up to a maximum of 10 bytes (so it's
less efficient than a fixed 8 bytes if you mostly have very large numbers).
It's quite simple but effective. We could [borrow
it|https://github.com/apache/avro/blob/branch-1.3/lang/java/src/java/org/apache/avro/io/BinaryEncoder.java#L192-L199]
if we want.
