insertPrimaryWithNulls
fun insertPrimaryWithNulls(schema: TableSchema, entity: Any, ttlSeconds: Int? = null, ifNotExists: Boolean = false, timestampMicros: Long? = null, consistency: KandraConsistency? = null): BoundStatement
Same as insertPrimary but binds null as actual null (creates tombstones). Use when the caller explicitly wants to clear optional columns.
