Attending: Josh M., Gregg L, Davis B., Hailey J., John K., Ward F., Ryan W.

• Sharding

  • Davis: excited about the implementation

  • Josh: anything you would change?

    • Davis: listen to what Jeremy is saying (pretty authoritative)
    • No group metadata in neuroglancer pre-computed
    • see his tensorstore implementation
  • JM: Worth chatting with Jeremy? DB: dialog with scalableminds,

    looks like it’s wondering

  • JM: also thinking about investigating sharding in V3 (as an

    extension)?

    • GL: would need to look at whether or not it’s in place. have implemented the necessary methods, but that’s not a guarantee.

• Logo: pink!

  • Should be finalized soon.

• HJ: poster coming

  • add to https://zarr-developers.github.io/? Sure.

• WF: handing proposal draft in the next few hours!!

  • also another poster (compression plugin implementation)

  • JM:

    https://github.com/zarr-developers/numcodecs/issues/298 FYI

  • WF: collaborating with NOA UC Irvine, etc. on lossy compression

    codec

• for GL: when to do 2.11?

  • PRs opened is everything for V3 (part 6 has all of it)

  • Store V3, then attributes, then array, then group, convenience

  • [*Store

    V3*](https://github.com/zarr-developers/zarr-python/pull/874) should be safe. Follow ups add key word.

  • Issue is test coverage (80%)

    • rmdir() outside of the class aren’t tested yet.

  • Tests needed a bit of updating to override create_store

    • (to set a path or check for “metadata/$path”)

  • alpha testers maybe…

  • to see what’s currently in 2.11:

    https://github.com/zarr-developers/zarr-python/blob/master/docs/release.rst

• JK: default of write_empty?

  • https://github.com/zarr-developers/zarr-python/pull/853

  • JM: just quick and dirty benchmark. @@DB

  • DB: Add some documentation? Depends on the contents of the array

  • JK: go beyond docs. Maybe even have a blurb / blog post. include

    benchmark.

    • and release notes.

• also re: 2.11

  • Dimitri?

    • Nice cleanups. Maybe bundle PRs? (largely due to notifications)

  • GL: can test the alpha (also to check the napari repo)

  • see
