pub struct VersionedLookupState {
pub batch: RecordBatch,
pub index: Arc<VersionedIndex>,
pub key_columns: Vec<String>,
pub version_column: String,
pub stream_time_column: String,
}Expand description
State for a versioned (temporal) lookup table.
Holds all versions of all keys in a single RecordBatch, plus a
pre-built VersionedIndex for efficient point-in-time lookups.
The index is built once at registration time and rebuilt only when
the table is updated via CDC.
Fields§
§batch: RecordBatchAll rows (all versions) concatenated into a single batch.
index: Arc<VersionedIndex>Pre-built versioned index (built at registration time, not per-cycle).
key_columns: Vec<String>Primary key column names for the equi-join.
version_column: StringColumn containing the version timestamp in the table.
stream_time_column: StringStream-side column name for event time (the AS OF column).
