| Performance with large data | 15 | Recent versions of JupyterLab/Notebook improve UI performance. Large outputs freezing the browser can be prevented by using visualisation and tabulation libraries that make use of rasterization and canvas renderers (e.g. plotly, ipydatagrid or newcomers like xy). Third-party extensions streamline work with large dataset in dedicated big data formats (e.g. jupyterlab-h5web for HDF5, NeXus, ANNData, etc; Arbalister for Parquet, CSV, Avro, ORC, SQLite, Arrow IPC). |
| Documentation and discoverability | 14 | Jupyter documentation and Discourse. We are aware that changelogs and breaking-change notes are missing or inconsistent across subprojects, and this needs addressing. |
