Alert and suppression updating in a cluster computing system

A computing device, comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to perform operations including:
• presenting, in an interface, a first set of alert records stored in a shared alert data store that is shared amongst a cluster of processing nodes,
• receiving, from the interface, a request to delete an identified alert record from the first set of alert records,
• adding, responsive to the request to delete the identified alert record, a new delete alert record to the shared alert data store, the new delete alert record uniquely identifying the identified alert record to the shared alert data store and comprising an annotation identifying the new delete alert record as being a delete alert record,
• deleting the identified alert record from the shared alert data store responsive to the request to delete the identified alert record, and
• transmitting, after adding the new delete alert record to the shared alert data store, the new delete alert record to a first processing node of the cluster of processing nodes, wherein the first processing node:
• matches, responsive to the annotation, the new delete alert record to a local copy of the identified alert record based on the new delete alert record uniquely identifying the identified alert record, and
• deletes, based on the annotation, the local copy of the identified alert record according to the delete alert record.
