- 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
