• object_store
  object_store

  Retry extension for ObjectStore
• storage_constants
  Storage option keys to use when creating ObjectStore. The same key should be used whether passing a key in the hashmap or setting it as an environment variable. Must be implemented for a given storage provider
• utils
  Utility functions for working across Delta tables

Structs

• GetResult
  Result for a get request
• ListResult
  Result of a list call that includes objects, prefixes (directories) and a token for the next set of results. Individual result sets may be limited to 1,000 objects based on the underlying object storage’s limitations.
• ObjectMeta
  The metadata that describes an object.
• Path
  A parsed path representation that can be safely written to object storage
• StorageOptions
  Options used for configuring backend storage

Enums

• ObjectStoreError
  A specialized Error for object store-related errors

Constants

• DELIMITER
  The delimiter to separate object namespaces, creating a directory structure.

Traits
