- Meeting Minutes

    - Micah: new results with v3 zarr writer
        - compression ratio is still weird (2 for all zarr types, including uncompressed)
        - dropped frames: zstd drops the least, the number of dropped frames is concerning
        - transfer speed makes sense now (files are similar/same size regardless of chunk size), mostly keeping up with Tiff
        - prior results: zstd typically compresses more but is slower than lz4, but this is not we see here
        - summary: generally the result we want, but still some mysteries, and number of dropped frames is concerning (especially for larger chunks)
            - zstd with big shards can do ~500MB/s (still needs verification)
    - Alan: tczyx dimensions, picking append dimension
        - initial feedback on proposal
        - Adam: we are appending over z only
            - c could be interesting
            - good to have flexibility
        - Micah: more amenable to different people's approaches
    - Alan: acquisition workshop invite list
        - Adam and Nathan need to meet
    - Alan: github runner egrabber
        - Adam: can give remote access to a egrabber compat camera (linescan)
        - Adam: have the camera that was being used, so can set that up with a github runner

- Action Items
    - Micah/Alan: coordinate on solving remaining mysteries from zarr experiments
    - Adam: email Nathan to start on workshop invite list
