ODD PI 25.4 Objective 4: 🛠️ Zarr Development

[abarciauskas-bgse]

Motivation

Zarr and zarr-python are currently under supported, yet NASA teams and data users are continuing to rely on and expect Zarr to provide collection-level analysis-ready data. We have an obligation to support the stability and feature development of Zarr and zarr-python for NASA to have continued expansive use of its products.

Description

See AC

Acceptance Criteria

• Support zarr-python 3 through regular maintenance, triaging issues
• Develop specification and prototype implementation for variable-chunks (either in shape or encoding), see also Zarr extension for stacked / concatenated virtual views · Issue #288 · zarr-developers/zarr-specs · GitHub
• Quantify the impact of Zarr improvements for future NASA architecture.
