description: >
Specifies the maximum number of active user index builds that can be built simultaneously on
the primary node. Index builds initiated by the system are not subject to this limitation.
Additionally, active index builds initiated by the system count towards the limit and can
delay scheduling user index builds even when the number of active user index builds is below
the limit.

resumableIndexBuildMajorityOpTimeTimeoutMillis:
description: >
Time in milliseconds a node waits for the last optime before installing the interceptors to
be majority committed for a resumable index build. Once the interceptors are installed, the
index build process will start the collection scan phase.
If the majority commit point is not reached by the end of this waiting period, the index
build will proceed as a non-resumable index build.
Set to 0 to skip the wait. This will also disable resumable index builds.
Set to a negative value to wait indefinitely for the majority commit point.
