-Two tables are registered; a transaction input table, and a spend report
output table.
-The transactions (`transactions`) table lets us read credit card transactions,
which contain account ID's (`accountId`), timestamps (`timestamp`), and US$
amounts (`amount`).
-In this tutorial, the table is backed by data generated in memory to avoid any
dependencies on external systems.
-In practice, the `BoundedTransactionTableSource` may be backed by a
filesystem, a database, or any other static source.
-The spend report (`spend_report`) table logs each row with log level **INFO**,
instead of writing to persistent storage, so you can easily see your results.
+在上面的代码中，你注册了两张表。一张"transaction"表作为输入表，还有一张"spend_report"作为输出表。
+我们可以从`transactions`表中读取信用卡的交易记录，其中包含了账号ID字段（`accountId`）字段、时间戳（`timestamp`）字段和交易金额（`amount`）字段。
+在这个教程中，`transactions`表中的数据都是在内存中生成的，不需要依赖任何外部数据库。
