Manage In-Progress Index Creation

View Index Creation Operations

To see the status of an indexing process, you can use the db.currentOp() method in the mongo shell. To filter the current operations for index creation operations, see Active Indexing Operations for an example.

The msg field will include the percent of the build that is complete.

Terminate Index Creation

To terminate an ongoing index build, use the db.killOp() method in the mongo shell. For index builds, the effects of db.killOp() may not be immediate and may occur well after much of the index build operation has completed.

You cannot terminate a replicated index build on secondary members of a replica set. To minimize the impact of building an index on replica sets, see Build Indexes on Replica Sets.

Changed in version 2.4: Before MongoDB 2.4, you could only terminate background index builds. After 2.4, you can terminate both background index builds and foreground index builds.
