Hi @richardwolford-7948
Unfortunately, there is no trigger for Azure Redis Cached for azure function. Only supported bindings are listed here.
I do see this as the feature request and the product team confirmed that there are no plans for direct support but aim to make it possible via Azure Event Grid which is planned in the future but currently, there is no ETA.
Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community looking for help on similar topics.
