I wanted to open this PR up to start a discussion around whether this would be an interesting example to include in this repository, and/or whether it might be worth...

Cost of sorting sparse array coordinates

I’m looking to store DataFrames as sparse arrays using TileDB but have a few questions about performance. Provided my query intercepts only a single fragment, everything seems nice and fast....

Idea: include a bloom filter in sparse array MBRs

1

My own motivation for this comes from modelling labelled dimensions with dictionary encoding. e.g. I have labels A: 0, B: 1, C: 2. When slicing an array for label B...

Null tile extent checks prevent full domain for unsigned integral types

1

It's not clear to me what this check is trying to do. For signed types, the tile extent is greater than the numeric limits max, but for unsigned types, this...

Maximum fragment size consolidation parameter

2

There's an example in the docs of how consolidation can somewhat approximate LSM trees. It would be helpful when operating in such a mode (consolidating after every write) to define...

Array is unreadable with string dimension containing only empty strings

1

With only empty strings `auto size = s1.size() + s2.size();` is zero, which results in an exception when fetching the array_fragments or fetching the nonempty domain, unfortunately making the array...

py4j.java_gateway.launch_gateway java_path argument should default to None

## What happened? I have a constructor that accepts a Foo, where Foo implements/extends Bar. My class only uses methods from Bar though, so the argument it accepts is overly...
