Fields§

§table_files_statistics_cache: Option<Arc<dyn CacheAccessor<Path, Arc<Statistics>, Extra = ObjectMeta>>>

Enable cache of files statistics when listing files. Avoid get same file statistics repeatedly in same datafusion session. Default is disable. Fow now only supports Parquet files.

§list_files_cache: Option<Arc<dyn CacheAccessor<Path, Arc<Vec<ObjectMeta>>, Extra = ObjectMeta>>>

Enable cache of file metadata when listing files. This setting avoids listing file meta of the same path repeatedly in same session, which may be expensive in certain situations (e.g. remote object storage). Note that if this option is enabled, DataFusion will not see any updates to the underlying location.
Default is disable.
