What's Wrong?
使用Zorder排序后,当第一列作为过滤列时,查询结果为全表查询,非过滤结果
-- Zorder排序表,建表sql
CREATE
TABLE
ZORDER_TEST(
`S_ID` BIGINT,
`S_SUPPKEY` BIGINT ,
`S_NAME` CHAR(25) ,
`S_ADDRESS` VARCHAR(40) ,
`S_NATIONKEY` BIGINT ,
`S_PHONE` CHAR(15) ,
`S_ACCTBAL` DOUBLE ,
`S_COMMENT` VARCHAR(117)
) ENGINE = OLAP
DUPLICATE KEY(`S_ID`, `S_SUPPKEY`)
COMMENT 'OLAP' DISTRIBUTED BY HASH(`S_ID`) BUCKETS 10
PROPERTIES(
"replication_allocation" = "tag.location.default: 1" ,
"data_sort.sort_type" = "ZORDER" ,
"data_sort.col_num" = "2" ,
"in_memory" = "false" ,
"storage_format" = "V2" ,
"disable_auto_compaction" = "false"
)
;建表sql参考自 #7149
数据来源,通过脚本生成test_data.csv文件
#!/usr/bin/env python
# coding=utf-8
import random
import csv
with open('test_data.csv', 'w', newline='') as csvfile:
fieldnames = ['S_ID', 'S_SUPPKEY', 'S_NAME', 'S_ADDRESS', 'S_NATIONKEY', 'S_PHONE', 'S_ACCTBAL', 'S_COMMENT']
writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
for i in range(1000000):
writer.writerow({
'S_ID': i,
'S_SUPPKEY': random.randint(1, 1000000),
'S_NAME': f'Supplier_{i}',
'S_ADDRESS': f'Address_{random.randint(1, 100)}',
'S_NATIONKEY': i+10086,
'S_PHONE': f'{random.randint(100, 999)}-{random.randint(100, 999)}-{random.randint(1000, 9999)}',
'S_ACCTBAL': round(random.uniform(-10000, 10000), 2),
'S_COMMENT': f'Comment_{i}'
})csv加载数据
curl --location-trusted -u root: -T test_data.csv -H "column_separator:," http://127.0.0.1:8030/api/demo/ZORDER_TEST/_stream_load过滤查询
select * from ZORDER_TEST where S_ID=181818;What You Expected?
- Zorder排序表第一列可以作为过滤列正常查询,若不可以给出原因;
- Zorder排序表缺少详细介绍,应用场景,使用是否有什么限制等等,可否详细介绍下。
