Peter Schuller commented on CASSANDRA-3895:
-------------------------------------------
Are you saying it is, by definition? If so I don't understand it at all. I
thought "fat client" was supposed to refer to a client that joins the gossiping
in order to be kept up-to-date with ring information for request routing
purposes. I don't understand how a bootstrapping node is in any way supposed to
be considered a fat client. Fat clients aren't supposed to receive writes
(right?), and are not expected to enter the ring and serve reads.

> There is code for fat client removal and "old" endpoint (non-fat) removal
> which uses {{TokenMetadata.isMember()}} which only considers nodes that are
> joined (takes reads) in the cluster.
> aVeryLongTime is set to 3 days.
> I could very well be wrong, but the fat client identification code, the way I
> interpret it, is using isMember() to check basically whether a node is "part
> of the cluster" (in the most vague/broad sense) in order to differentiate a
> "real" node (part of the cluster) from just a fat client. But a node that is
> boot strapping is not a fat client, nor will be me a member according to
> isMember().
> I'm also a bit scared of, even in the case of there not being a fat client
> identification, simply forgetting an endpoint. It seems that an operator
> request should be relied upon to actively forget an endpoint (i.e., forced
> remove token).
