DefaultJdbcSplittableSnapshotWithCursorPartition

class DefaultJdbcSplittableSnapshotWithCursorPartition(val selectQueryGenerator: SelectQueryGenerator, val streamState: DefaultJdbcStreamState, primaryKey: List<Field>, val lowerBound: List<JsonNode>?, val upperBound: List<JsonNode>?, val cursor: Field, cursorUpperBound: JsonNode?) : DefaultJdbcCursorPartition

Default implementation of a JdbcPartition for a splittable snapshot partition preceding a cursor-based incremental sync.
