setIndexCommitQuorum

setIndexCommitQuorum

Changes the minimum number of data-bearing members (i.e commit quorum), including the primary, that must complete an in-progress simultaneous index build before the primary marks those indexes as ready.更改数据承载成员的最小数量（即提交仲裁），包括主要成员，这些成员必须在主要成员将这些索引标记为就绪之前完成正在进行的同步索引构建。

The command has the following syntax:该命令具有以下语法：

db.runCommand({
  setIndexCommitQuorum: <string>,
  indexNames: [ <document> ],
  commitQuorum: <int> | <string>,
  comment: <any>
})

The command takes the following parameters:该命令采用以下参数：

Field字段	Type类型	Description描述
setIndexCommitQuorum	string	The name of the collection for which the indexes are being built.正在为其生成索引的集合的名称。
indexNames	array	An array of in-progress index builds to modify. 要修改的正在生成索引的数组。Each element of the array must be the name of the index.数组的每个元素都必须是索引的名称。 The indexes specified to indexNames must be the entire set of in-progress builds associated to a given index builder, i.e. the indexes built by a single createIndexes or db.collection.createIndexes() operation.指定给indexNames的索引必须是与给定索引生成器关联的整个正在进行的生成集，即通过单个createIndexes或db.collection.createIndexes()操作生成的索引。
commitQuorum	int or string	The minimum number of data-bearing voting replica set members (i.e. commit quorum), including the primary, that must report a successful index build before the primary marks the indexes as ready. 包含投票副本集成员（即提交仲裁）的数据承载的最小数量，包括主成员，必须在主成员将indexes标记为就绪之前报告成功的索引生成。A "voting" member is any replica set member where members[n].votes is greater than 0.“投票”成员是members[n].votes大于0的任何复制集成员。 Starting in MongoDB v5.0 it is possible to resume some interupted index builds when the commit quorum is set to "votingMembers".从MongoDB v5.0开始，当提交仲裁设置为“votingMembers”时，可以恢复一些中断的索引构建。 The "votingMembers" commit quorum cannot be used if any voting replica set node is configured with members[n].buildIndexes set to false. 如果任何投票副本集节点的members[n].buildIndexes设置为false，则无法使用"votingMembers"提交仲裁。Either configure all nodes with members[n].buildIndexes set to true or select a commit quorum that requires fewer votes.配置members[n].buildIndexes设置为true的所有节点，或选择需要更少投票的提交仲裁。 Supports the following values: "votingMembers" - all data-bearing voting replica set members. (Default)所有数据承载投票复制集成员。（默认） "majority" - a simple majority of data-bearing voting replica set members.简单多数数据承载投票副本集成员。 <int> - a specific number of data-bearing voting replica set members. 特定数量的数据承载投票复制集成员。Specify an integer greater than 0.指定一个大于0的整数。 A replica set tag name.副本集标记名。
comment	any	Optional. 可选。A user-provided comment to attach to this command. 用户提供了附加到此命令的注释。Once set, this comment appears alongside records of this command in the following locations:设置后，此注释将与此命令的记录一起显示在以下位置： mongod log messages, in the attr.command.cursor.comment field.mongod日志消息，在attr.command.cursor.comment字段中。 Database profiler output, in the command.comment field.数据库探查器输出，在command.comment字段中。 currentOp output, in the command.comment field.currentOp输出，在command.comment字段中。 A comment can be any valid BSON type(string, integer, object, array, etc).注释可以是任何有效的BSON类型（字符串、整数、对象、数组等）。 New in version 4.4.在版本4.4中新增。

  [
    { "invoices" : 1 },
    { "fulfillmentStatus" : 1 }
