how to downsample isotropically

5

is it possible to apply downsampling in all three spatial dimensions? I have isotropic data, so it makes sense to do this.

- ensures that the `fill_value` of a v3 array is an instance of that array's dtype. The behavior here matches numpy type casting rules, so if `dtype` is `bool` and...

If port 5555 is in use, then the remote store tests hang forever. ``` Address already in use Port 5555 is in use by another program. Either identify and stop...

- Adds dunder methods to `ShardingCodec` to enable pickling, and adds a simple test for this - refactors the codecs test suite. this is the start of a larger effort....

This PR adds a declarative API for defining Zarr arrays and groups independently of storage. Using this API, users and developers can create and manipulate Zarr hierarchies, adding nodes and...

use compressor, filters, post_compressor for Array v3 create

16

In terms of abstraction levels, this pushes the `codecs` kwarg below the array creation API. Instead, we use the kwarg "filters" to denote ArrayArray codecs, "compressor" to denote the ArrayBytes...

JSON -> dict[str, JSON]

6

Some functions that return `dict[str, JSON]` were mistakenly annotated as returning `JSON`. One wrinkle to this PR is the `BatchedCodecPipeline` class, where `from_dict` takes a list, and `to_dict` returns a...

Because it uses [`lru_cache`](https://github.com/zarr-developers/zarr-python/blob/e3ee09eaa8a5e17a92d00ae4979aa069f755eaba/src/zarr/codecs/sharding.py#L323-L325) and we have not implemented the requisite dunder methods for object serialization to make it pickleable, which is not hard according to [internet wisdom](https://stackoverflow.com/a/73785520) . todo:...

[v3] skew in store class attributes

1

`LocalStore` has a [`root`](https://github.com/zarr-developers/zarr-python/blob/194862802e2d31191a49a291b294807755e5b8d6/src/zarr/store/local.py#L72) attribute, but `RemoteStore` has a [`path`](https://github.com/zarr-developers/zarr-python/blob/194862802e2d31191a49a291b294807755e5b8d6/src/zarr/store/remote.py#L28) attribute. I believe they have the same function. We should eventually pick one name for this, and figure out how...
