Generic Streaming Allocations

These default allocations apply to consumers of generic streaming.

Description	Performance and Unlimited Editions	Enterprise Edition	Professional Edition	Free Orgs
Maximum streaming channels per org	1,000	1,000	1,000	200
Maximum number of concurrent clients (subscribers) across all channels and for all event types	2,000	1,000	20	20
Maximum number of delivered event notifications within a 24-hour period, shared by all CometD clients, with Durable Generic Streaming (API version 37.0 and later)	1,000,000	200,000	100,000	10,000
Maximum number of delivered event notifications within a 24-hour period, shared by all CometD clients, with generic streaming (API version 36.0 and earlier)	100,000	100,000	100,000	10,000

Free orgs include Developer Edition orgs and trial orgs (all editions), such as partner test and demo orgs created through the Environment Hub. Sandboxes get the same allocations as their associated production orgs.

Note

If you exceed the default event delivery allocation, you receive this error: 403::Organization total events daily limit exceeded. The error is returned in the Bayeux /meta/connect channel when a CometD subscriber first connects or in an existing subscriber connection. For more information, see Streaming API Error Codes. Generic event notifications that are generated after exceeding the allocation are stored in the event bus. You can retrieve stored event messages as long as they are within the retention window of 24 hours.

If you have scenarios that warrant an increase in the number of delivered event notifications within a 24-hour period, contact Salesforce.
