示例1: queryNextPage

protected List<Row> queryNextPage(int pageSize, ConsistencyLevel consistencyLevel, boolean localQuery)
throws RequestValidationException, RequestExecutionException
{
// For some queries, such as a DISTINCT query on static columns, the limit for slice queries will be lower
// than the page size (in the static example, it will be 1). We use the min here to ensure we don't fetch
// more rows than we're supposed to. See CASSANDRA-8108 for more details.
