We're excited to announce a new beta feature in conda called sharded repodata. This optimized repodata format makes environment solves faster by reducing the time spent fetching package metadata. Conda-forge is already serving sharded repodata, so you can try it immediately when using conda with conda-forge. In this post, we'll show you how to enable it, explain how the work came together across the ecosystem, and share the performance improvements you can expect in everyday use.

Over a year ago, the conda team at Anaconda, together with conda developers at Quansight and QuantStack, announced the release of a new solver for conda based on the libraries that the mamba project had developed on top of the venerable libsolv project.

TL;DR​

• From July 2023 on, conda-libmamba-solver will be part of the various installers. The default conda solver is still classic. Look out for the release of miniconda, Anaconda Distribution and miniforge soon.
• From September 2023 on, the default conda solver will be libmamba. classic will be available via --solver=classic, if needed.
• At some point in the future, we'll discuss whether the classic solver is kept around, maintained as a separate plugin, and/or deprecated for good. Feedback welcome!
