[GitHub] [doris] nextdreamblue opened a new issue, #15560: [Bug] do not set default replication_allocation when restore with property "reserve_replica" = "true"
nextdreamblue opened a new issue, #15560:
URL: https://github.com/apache/doris/issues/15560
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
### Version
master
### What's Wrong?
when restore a table with property "replication_num" = "n", it will set property of the table restored "replication_allocation" = "tag.location.default: n", but if restore the table with property "reserve_replica" = "true", it do not need set "replication_allocation" = "tag.location.default: n", and it needs reserve the replication_allocation before backup.
### What You Expected?
do not set default replication_allocation when restore with property "reserve_replica" = "true"
### How to Reproduce?
建表及恢复语句：
CREATE TABLE `array_test` (
`id` int(11) NULL,
`c_array` array<int(11)> NULL
) ENGINE=OLAP
DUPLICATE KEY(`id`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`id`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 3",
"in_memory" = "false",
"storage_format" = "V2",
"disable_auto_compaction" = "false"
);
BACKUP SNAPSHOT hugo.array_test
TO hugo_bak
ON (array_test)
PROPERTIES ("type" = "full");
RESTORE SNAPSHOT hugo_bak.`array_test`
FROM `tencent_doris_backup`
ON ( `array_test` )
PROPERTIES
(
"backup_timestamp"="xxxxxxxx",
"replication_num" = "2",
"reserve_replica" = "true"
);
按照文档描述，设置了"reserve_replica" = "true"，会忽略 replication_num 属性，恢复的表或分区的副本数将与备份之前一样。
但是这样设置后恢复的表 replication_allocation 值为 replication_num，不会忽略。
show create table array_test;
CREATE TABLE `array_test` (
`id` int(11) NULL,
`c_array` array<int(11)> NULL
) ENGINE=OLAP
DUPLICATE KEY(`id`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`id`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 2",
"in_memory" = "false",
"storage_format" = "V2",
"disable_auto_compaction" = "false"
);
