hive driver for go
已解决!
可以加入代码依赖吗?
问题:批处理数据量最高只能是10000,该如何设置得更高?
目标:如果我想要处理12000条数据,我rs.Next()只能拿到10000条,后面的2000条该怎么拿到呢?
描述:发现了batchsize批处理参数默认设置为10000,可以减少,但不可以增加,似乎10000是上限。rs.Next()处理到10000就已经为空了.
该如何解决?大佬可以提供个思路吗?

Please, help to solve problem.
想问下如何通过gohive来获取表的大小。
rs, err := conn.Query("desc formatted " + tableName)
for rs.Next() {
rs.Scan(&resultLine)
// 获取表大小
}
但是这样是报错的,想问下这种非关系型的结果应该怎么读取出来呢?
"Can't scan into 1 arguments with input of length 3"
