Required Privileges for MongoDB

Overview

To migrate or sync data from or to MongoDB instances, BladePipe requires certain user permissions to be granted.

信息

The permission requirements are also applicable to Aliyun MongoDB and AWS DocumentDB.

As the Source

• Full Data: SELECT permission for the collections to be migrated.
  e.g.:

    db.createRole({
        role: "sync",
        privileges: [
            {
                resource: { db: "", collection: "" },
                actions: ["listCollections", "listDatabases", "listIndexes"]
            }],
        roles: []
    });

• Incremental: ChangeStream permission for MongoDB instance.
  e.g.:

    db.createRole({
        role: "sync",
        privileges: [
            {
                resource: { db: "", collection: "" },
                actions: ["find", "changeStream"]
            }],
        roles: []
    });

  信息

  If the data source is AWS DocumentDB, you should also add modifyChangeStreams and listChangeStreams to the action, as shown below:

    db.createRole({
        role: "sync",
        privileges: [
            {
                resource: { db: "", collection: "" },
                actions: ["find", "changeStream", "modifyChangeStreams", "listChangeStreams"]
            }],
        roles: []
    });

• Heartbeat (optional): SELECT, INSERT and UPDATE permissions for the heartbeat database.
  e.g.:

    db.createRole({
        role: "sync",
        privileges: [
            {
                resource: { db: "", collection: "" },
                actions: ["insert", "update", "listCollections", "listDatabases", "listIndexes"]
            }],
        roles: []
    });

As the Target

Full Data/Incremental: INSERT, UPDATE and DELETE permissions for the collections to be migrated.
e.g.:

  db.createRole({
      role: "sync",
      privileges: [
          {
              resource: { db: "", collection: "" },
              actions: ["insert", "update", "delete"]
          }],
      roles: []
  });
