Another status update. I've integrated the level generation code with the
parquet writing code [1].
After that PR is merged I'll add bindings in Python to control versions of
the level generation algorithm and plan on moving on to the read side.
Thanks,

Generally Ive found that this isnt an important optimization in the use
cases we see. Memory overhead, especially with our Java shared allocation
scheme is nominal. Optimizing null checks at the word level usually is much
more impactful since non null and null runs are much more common on a

hi folks,
There has periodically been a discussion about employing dedicated
compute resources to serve our testing needs beyond what can be
accomplished in free / public CI services like GitHub Actions,
Appveyor, etc. For example:

* Tests requiring a lot

While the underlying storage may allow duplicate keys, it seems much more
likely that someone would end up with duplicate keys by accident than by
design. And although it may be up to the implementations to determine or

I think it's ok for the convenience API to return a dict, if we also
expose e.g. a "metadata_items" that returns an it

In the C++ library at least, uniqueness is never asserted when reading
and writing the IPC metadata [1] [2]. If you use
KeyValueMetadata::FindKey and the keys are non-unique, it will return
the first one it finds. KeyValueMetadata::Merge assumes uniqueness,
and the KeyValueMetadata::ToUnorderedMap

Computation speed needs to be thought about in context We might find
something which takes up half the space to be a little more computationally
expensive, but in the grand scheme of things is faster to compute as more of it
can fit in memory, and it saves I/O. I definitely a
