}Expand description
State for a partial (on-demand) lookup table.
Fields§
§foyer_cache: Arc<FoyerMemoryCache>Bounded foyer memory cache with S3-FIFO eviction.
schema: SchemaRefSchema of the lookup table.
key_columns: Vec<String>Key column names for row encoding.
key_sort_fields: Vec<SortField>SortField descriptors for key encoding via RowConverter.
source: Option<Arc<dyn LookupSourceDyn>>Async source for cache miss fallback (None = cache-only mode).
fetch_semaphore: Arc<Semaphore>Limits concurrent source queries to avoid overloading the source.
