我们正在使用聚合查询从表中获取大量数据。 它工作正常，但肯定会在cassandra日志中引发以下错误：-

无法完全确定错误。

使用的cql查询：
SELECT ean, condition, sum(stock) as stock FROM article_supplier_info WHERE start_date <= currentDate AND expire_date > currentDate AND stock > 0 GROUP BY ean, condition ALLOW FILTERING
答案 0 :(得分：0)
这不是答案，而只是一个建议。
不是专家，但是通过查看code似乎在以下代码块中失败了：
public void add(Row row) { if (row.isEmpty()) return; if (row.isStatic()) { // this assert is expensive, and possibly of limited value; we should consider removing it // or introducing a new class of assertions for test purposes assert columns().statics.containsAll(row.columns()) : columns().statics + " is not superset of " + row.columns(); staticRow = staticRow.isEmpty() ? row : Rows.merge(staticRow, row); } else { // this assert is expensive, and possibly of limited value; we should consider removing it // or introducing a new class of assertions for test purposes assert columns().regulars.containsAll(row.columns()) : columns().regulars + " is not superset of " + row.columns(); rowBuilder.add(row); } }
我希望这可以帮助您在代码中查找问题。
