Configuration for decoder behavior

Fields

cache_repetition_index: bool

Whether to cache repetition indices for better performance.

This defaults to the LANCE_READ_CACHE_REPETITION_INDEX environment variable when present and is enabled by default. Set the env var to a non-truthy value (for example 0 or false) to disable it. The env var is read once per process.

validate_on_decode: bool

Whether to validate decoded data

inline_scheduling: Option<bool>

Override the strategy used to dispatch the scheduling work in schedule_and_decode.

schedule_and_decode always awaits the scheduler’s initialize (which performs metadata I/O) before returning. This flag controls what happens with the subsequent (synchronous) work of pushing decoder messages into the channel that feeds the decode stream.

• None - default behavior: the scheduling work runs inline (as part of the schedule_and_decode await) when the request is small (controlled by the LANCE_INLINE_SCHEDULING_THRESHOLD env var) and is dispatched onto a spawned task otherwise.
• Some(true) - always run scheduling inline. The await of schedule_and_decode does not return until every decoder message has been queued.
• Some(false) - always spawn a task for scheduling so that it can overlap with consumption of the decode stream.
