Resource	Limit	Description
Event per request	50	Maximum number of events pushed in a single request.
Event per minute	500	Maximum number of events pushed in one minute.
Payload size	200 KB	Maximum combined payload size of events in single request.
Retry data size	4 KB	Maximum size of `retryData`. This will be enforced from `Nov 13, 2025`. See CHANGE-2508 for more details.
Payload size for long running functions	100 KB	Maximum size of an individual event. This limit only applies to functions specifying a timeout greater than 55 seconds.
Retry data size for long running functions	4 KB	Maximum size of `retryData`. This limit only applies to functions specifying a timeout greater than 55 seconds.
Cyclic invocation limit	1000	An event resolver can push more events to the queue, which may trigger further event handlers in a chain. This limit applies to the total number of async event push requests that can be made across all handlers originating from a single initial function invocation, including requests made by downstream handlers. Each push request can contain up to 50 events. For example, a function that calls push 1000 times in a loop, or a chain where each handler calls push once for 1000 hops, both reach this limit.
