context · object

Arbitrary context for a request as key-value pairs. How to use the context is custom to the specific implementation.

REST NAMESPACE ONLY Context entries are passed via HTTP headers using the naming convention x-lance-ctx-<key>: <value>. For example, a context entry {"trace_id": "abc123"} would be sent as the header x-lance-ctx-trace_id: abc123.

Required range: x >= 0

Show child attributes

naming_scheme · string

The naming scheme used for manifest files in the _versions/ directory.

Known values:

• V1: _versions/{version}.manifest - Simple version-based naming
• V2: _versions/{inverted_version}.manifest - Zero-padded, reversed version number (uses u64::MAX - version) for O(1) lookup of latest version on object stores

V2 is preferred for new tables as it enables efficient latest-version discovery without needing to list all versions.

Example:

"V2"
