KYLIN-5371 fix segment prune

Open liuzhao-lz opened this issue 2 years ago • 2 comments

Proposed changes

创建model时在partition部分指定了天分区和时分区,格式分别为:yyyy-MM-dd、HH,在根据天分区值查询时结果非预期。原因是这种场景下segment裁剪有bug。

--不加天分区过滤得到的结果(18号3条数据,19号5条数据) 1e9077f923e57f65e3712b75d639a31

--加天分区在修复前查询结果 --18号实际有3条数据 6bbf3bf08dea6b5a269d57c65b4a1b7 --19号实际有5条数据 e4046323d0a7a8521dae904c5030f26 --18号19号共有8条数据 6858ba031d6d44b050edc76a6e96251
