### Cassandra Sink Example for Streaming Tuple Data Type
-While storing the result with Java/Scala Tuple data type to a Cassandra sink,
it is required to set a CQL upsert statement (via setQuery('stmt')) to persist
each record back to the database. With the upsert query cached as
`PreparedStatement`, each Tuple element is converted to parameters of the
statement.
+在将结果通过 Java/Scala Tuple 数据类型存储到 Cassandra 接收器时，需要设置CQL upsert 语句（通过
setQuery('stmt')）将每条记录保存回数据库。将 upsert 查询缓存为 `PreparedStatement` 时，每个 Tuple
元素都将转换为语句的参数。
