 The `RepositoryConfig` object is used to configure the repository. For convenience, this can be constructed using some sane defaults:

 Icechunk uses Zstd compression to compress its metadata files. [`CompressionConfig`](./reference.md#icechunk.CompressionConfig) allows you to configure the [compression level](./reference.md#icechunk.CompressionConfig.level) and [algorithm](./reference.md#icechunk.CompressionConfig.algorithm). Currently, the only algorithm available is [`Zstd`](https://facebook.github.io/zstd/).

 Icechunk caches files (metadata and chunks) to speed up common operations. [`CachingConfig`](./reference.md#icechunk.CachingConfig) allows you to configure the caching behavior for the repository.
