# Zarr Sprint @ PyData Global 2022 ## Time and place 2nd December, `17:00-20:00` UTC ### Zoom Meeting Join Zoom Meeting https://us06web.zoom.us/j/83833047249?pwd=NkJxdlFBMDZQRHY5VHBDL3RkRG4xUT09 Meeting ID: 838 3304 7249 Passcode: 369963 ## Project Description Zarr is a data storage format for storing chunked, compressed N-dimensional arrays and associated metadata. Zarr is based on an open-source technical specification and has implementations in several languages. Zarr is generally used to store large datasets. In addition, there is a variety of compressors available to use via the [Numcodecs](https://github.com/zarr-developers/numcodecs/) library. - Store arrays in memory, on disk, inside a Zip file on any cloud storage - Read and write to an array concurrently from multiple threads or processes - Organize arrays into hierarchies via groups ## Sprint Focus For PyData Global 2022, we'll focusing on [good-first](https://github.com/zarr-developers/zarr-python/issues?q=is%3Aopen+is%3Aissue+label%3Agood-first-issue), [help-wanted](https://github.com/zarr-developers/zarr-python/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22), [documentation](https://github.com/zarr-developers/zarr-python/issues?q=is%3Aopen+is%3Aissue+label%3Adocumentation) issues. ## Maintainers for the sprint ### Josh Moore `GitHub`: https://github.com/joshmoore/ `Discord`: joshmoore#7588 `Bio`: Josh Moore is a research software engineer living in Germany. His primary professional focus is the [Open Microscopy Enviorment (OME)](https://www.openmicroscopy.org) which provides open-source infrastructure for accessing and sharing bioimaging data. (Like [really big images of fish embryoes](https://hms-dbmi.github.io/vizarr/?source=https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.1/4495402.zarr&viewState={%22zoom%22:-8.30553913434833,%22target%22:[460800,190464]})). A critical part of doing that is defining good file formats for such big images which is why he got involved in Zarr of which he's now a maintainer. Happy-life ABCs: aikido, books, coffee ### Sanket Verma `GitHub`: https://github.com/msankeys963/ `Discord`: msankeys963#0660 `Bio`: Sanket Verma takes care of community and OSS at Zarr as their Community Manager. He loves building communities, data science tools and products and has worked with startups, government and organisations. When he's not working he likes to play the violin and computer games and sometimes thinks of saving the world! ## Project links Contributing Guide: https://zarr.readthedocs.io/en/stable/contributing.html Zarr Tutorials: https://zarr.readthedocs.io/en/stable/tutorial.html Documentation: https://zarr.readthedocs.io/en/stable/index.html Project logo: https://github.com/zarr-developers/zarr-logo/releases/tag/2022-04-28 Website: https://zarr.dev/ V2 Specification: https://zarr.readthedocs.io/en/stable/spec/v2.html
