-# Min Load Replica Num
-
-Importing data requires more than half of the replicas to be written
successfully. However, it is not flexible enough and may cause inconvenience in
some scenarios.
-
-For example, in the case of two replicas, to import data, both replicas need
to be written successfully. This means that no replica is allowed to be
unavailable during the data import process. This greatly affects the
availability of the cluster.
-
-In order to solve the above problems, Doris allows users to set the minimum
number of write replicas. For the task of importing data, when the number of
replicas it successfully writes is greater than or equal to the minimum number
of replicas written, the import is successful.
-
-## Usage
-
-### Min load replica num for single table
-
-You can set the table property `min_load_replica_num` for a single olap table.
The valid value of this property must be greater than 0 and not exceed
`replication_num`（the number of replicas of the table）. Its default value is
-1, indicating that the property is not enabled.
-
-The `min_load_replica_num` of the table can be set when creating the table.
-
-```sql
-CREATE TABLE test_table1
-(
- k1 INT,
- k2 INT
-)
-DUPLICATE KEY(k1)
-DISTRIBUTED BY HASH(k1) BUCKETS 5
-PROPERTIES
-(
- 'replication_num' = '2',
- 'min_load_replica_num' = '1'
-);
-```
-
-For an existing table, you can use `ALTER TABLE` to modify its
`min_load_replica_num`.
-
-```sql
-ALTER TABLE test_table1
-SET ( 'min_load_replica_num' = '1');
-```
-
-You can use `SHOW CREATE TABLE` to view the table property
`min_load_replica_num`.
-
-```SQL
-SHOW CREATE TABLE test_table1;
-```
-
-The PROPERTIES of the output will contain `min_load_replica_num`. e.g.
-
-```text
-Create Table: CREATE TABLE `test_table1` (
- `k1` int(11) NULL,
- `k2` int(11) NULL
-) ENGINE=OLAP
-DUPLICATE KEY(`k1`)
-COMMENT 'OLAP'
-DISTRIBUTED BY HASH(`k1`) BUCKETS 5
-PROPERTIES (
-"replication_allocation" = "tag.location.default: 2",
-"min_load_replica_num" = "1",
-"storage_format" = "V2",
-"light_schema_change" = "true",
-"disable_auto_compaction" = "false",
-"enable_single_replica_compaction" = "false"
-);
-```
-
-### Global min load replica num for all tables
-
-You can set FE configuration item `min_load_replica_num` for all olap tables.
The valid value of this configuration item must be greater than 0. Its default
value is -1, which means that the global minimum number of load replicas is not
enabled.
-
-For a table, if the table property `min_load_replica_num` is valid (>0), then
the table will ignore the global configuration `min_load_replica_num`.
Otherwise, if the global configuration `min_load_replica_num` is valid (>0),
then the minimum number of load replicas for the table will be equal to
`min(FE.conf.min_load_replica_num, table.replication_num/2 + 1)`.
-
-For viewing and modification of FE configuration items, you can refer to
[here](../../../admin-manual/config/fe-config.md).
-
-### Other cases
-
-If the table property `min_load_replica_num` is not enabled (<=0), and the
global configuration `min_load_replica_num` is not enabled(<=0), then the data
import still needs to be successfully written to the majority replica. At this
point, the minimum number of write replicas for the table is equal to
`table.replication_num/2 + 1`.

-# 最小写入副本数
-
-默认情况下，数据导入要求至少有超过半数的副本写入成功，导入才算成功。然而，这种方式不够灵活，在某些场景会带来不便。
-
-举个例子，对于两副本情况，按上面的多数派原则，要想导入数据，则需要这两个副本都写入成功。这意味着，在导入数据过程中，不允许任意一个副本不可用。这极大影响了集群的可用性。
-
-为了解决以上问题，Doris允许用户设置最小写入副本数(Min Load Replica
Num)。对导入数据任务，当它成功写入的副本数大于或等于最小写入副本数时，导入即成功。
-
-## 用法
-
-### 单个表的最小写入副本数
-
-可以对单个olap表，设置最小写入副本数，并用表属性`min_load_replica_num`来表示。该属性的有效值要求大于0且不超过表的副本数。其默认值为-1，表示不启用该属性。
-
-可以在创建表时设置表的`min_load_replica_num`。
-
-```sql
-CREATE TABLE test_table1
-(
- k1 INT,
- k2 INT
-)
-DUPLICATE KEY(k1)
-DISTRIBUTED BY HASH(k1) BUCKETS 5
-PROPERTIES
-(
- 'replication_num' = '2',
- 'min_load_replica_num' = '1'
-);
-```
-
-对一个已存在的表，可以使用语句`ALTER TABLE`来修改它的`min_load_replica_num`。
-
-```sql
-ALTER TABLE test_table1
-SET ( 'min_load_replica_num' = '1');
-```
-
-可以使用语句`SHOW CREATE TABLE`来查看表的属性`min_load_replica_num`。
-
-```SQL
-SHOW CREATE TABLE test_table1;
-```
-
-输出结果的PROPERTIES中将包含`min_load_replica_num`。例如：
-
-```text
-Create Table: CREATE TABLE `test_table1` (
- `k1` int(11) NULL,
- `k2` int(11) NULL
-) ENGINE=OLAP
-DUPLICATE KEY(`k1`)
-COMMENT 'OLAP'
-DISTRIBUTED BY HASH(`k1`) BUCKETS 5
-PROPERTIES (
-"replication_allocation" = "tag.location.default: 2",
-"min_load_replica_num" = "1",
-"storage_format" = "V2",
-"light_schema_change" = "true",
-"disable_auto_compaction" = "false",
-"enable_single_replica_compaction" = "false"
-);
-```
-
-### 全局最小写入副本数
-
-可以对所有olap表，设置全局最小写入副本数，并用FE的配置项`min_load_replica_num`来表示。该配置项的有效值要求大于0。其默认值为-1，表示不开启全局最小写入副本数。
-
-对一个表，如果表属性`min_load_replica_num`有效（即大于0），那么该表将会忽略全局配置`min_load_replica_num`。否则，如果全局配置`min_load_replica_num`有效（即大于0），那么该表的最小写入副本数将等于`min(FE.conf.min_load_replica_num，table.replication_num/2
+ 1)`。
-
-对于FE配置项的查看和修改，可以参考[这里](../../../admin-manual/config/fe-config.md)。
-
-### 其余情况
-
-如果没有开启表属性`min_load_replica_num`（即小于或者等于0），也没有设置全局配置`min_load_replica_num`(即小于或等于0)，那么数据的导入仍需多数派副本写入成功才算成功。此时，表的最小写入副本数等于`table.replicatition_num/2
+ 1`。
