📝 Walkthrough

Walkthrough

The documentation for Serverless cluster usage limits was updated to specify a new limit of 10,000 connections per cluster. This change adds the connection limit to the list of existing limits, such as users, ACLs, and consumer groups, in the relevant documentation file. No other changes to functionality or procedures were introduced.

27-27: Unify numeric-formatting style for limits

Other limits in this list (5000, 100 MB/s, etc.) omit thousands separators, whereas this new entry uses a comma. For consistency, drop the comma (or add separators to all other values).

-* Connections: 10,000 
+* Connections: 10000

Also removes the trailing space after the number.

[NOTE]
====
* The partition limit is the number of logical partitions before replication occurs. Redpanda Cloud uses a replication factor of 3.
* Connections are regulated per broker for best performance. For example, with 3 brokers, there could be up to approximately 3,330 connections per broker.

The per-broker proportion is dynamic: if a customer requires 9000 connections on a broker and 500 on the other two, they don't experience any rate limiting.

10k is a global limit of total concurrent connections from customer clients to the serverless cluster.

@nicolaferraro Is it correct then that our connection limit works different for Serverless than it does for BYOC/Dedicated?

@nicolaferraro is the connection limit per broker? I didn't think so?

No, I'm saying the opposite 😄

The limit is global, per VCluster, there's no per-broker limit. It works differently from the Dedicated/BYOC case.
