Query management for indexer clusters in hybrid cloud deployments

A non-transitory computer-readable medium having computer-readable program code embodied therein for causing a computer system to perform a method for performing a query, the method comprising:

• transmitting a list of active indexers in an indexer cluster from a cluster master for receipt by a first search head, wherein the cluster master is communicatively coupled with the indexer cluster comprising a plurality of indexers;
• receiving a first slot request at the cluster master in response to a query from the first search head, wherein the first search head is operable to transmit the query to the active indexers for execution if granted a slot request;
• determining if the first slot request can be granted;
• and
• responsive to a determination that the first slot request can be granted, transmitting an indication of a grant for a slot to the first search head.

A system comprising:

• a processing device communicatively coupled with a memory and configured to:
• transmit a list of active indexers in an indexer cluster from a cluster master for receipt by a first search head, wherein the cluster master is communicatively coupled with the indexer cluster comprising a plurality of indexers;
• receive a first slot request at the cluster master in response to a query from the first search head, wherein the first search head is operable to transmit the query to the active indexers for execution if granted a slot request;
• determine if the first slot request can be granted;
• and
• responsive to a determination that the first slot request can be granted, transmit an indication of a grant for a slot to the first search head.
