Cassandra Datastax驱动程序在访问器上设置分页状态 [英] Cassandra Datastax Driver set paging state on Accessor

问题描述

我正在为Cassandra使用Datastax的可爱Java驱动程序。我试图将所有查询字符串封装到内置的访问器中进行映射，但是我需要能够设置查询的分页状态。

I'm using Datastax's lovely java driver for cassandra. I was trying to encapsulate all of my query strings into the built in accessors for mapping, but I require the ability to set the paging state for a query.

我看到了普通的语句（SimpleStatement）可以实现，但是我没有找到访问器的相应功能。它是否存在，或者我是否已跳过使用访问器来实现此功能？

I see that this is possible with a normal Statement (SimpleStatement), but I haven't found the corresponding functionality for an Accessor. Does it exist, or do I have skip using Accessors for this functionality?

推荐答案

我同意这真的很不错

目前使用此方法的一种方法是让您的访问者返回一条语句，即：

One way to work with this for now would be to have your accessor return a Statement, i.e.:

@Query("SELECT * FROM ks.tbl WHERE id = ?")
Statement getAllById(@Param("id") UUID userId);

然后从那里调用 setPagingState Statement 返回并执行。

And then from there you call setPagingState on the Statement returned and execute it.

我同意这并不像向Accessor提供分页状态作为参数那样好，所以我继续打开 JAVA-1103 。

I agree that this isn't as nice as providing the paging state as a parameter to the Accessor, so I went ahead and opened up JAVA-1103.
