Events up to 1 MB in Event Grid – public preview
Updated: 29 May, 2019
Event Grid now supports events of up to 1 MB in size. There are no configuration changes required, and this will work on existing event subscriptions. To try it out, just push larger events. Everything under 64 KB will be still be covered by our GA SLA.
The batch size limit for events sent to Event Grid as a JSON array is still 1 MB. Events over 64 KB will be charged in 64 KB increment (e.g. an event of 100 KB will be charged as though it is two separate events).
