As stated in the comment this is usually due to a resharding in progress so the client should be still redirected to the old node that will handle the redirection elsewhere.

The new code makes sure that the node slots bitmap is always consistent with the cluster->slots array.

Before a relatively slow popcount() operation was needed every time we needed to get the number of slots served by a given cluster node. Now we just need to check an integer that is taken in sync with the bitmap.

The new system detects a failure only when there is quorum from masters.

This is not very important as anyway when the function counting the number of reports is called the cleanup is performed. However with this change if only part of the nodes that reported the failure will report the node is back ok, we'll cleanup the older entries ASAP. In complex split net split scenarios, and when we are dealing with clusters having nodes in the order of ~ 1000, this can save some CPU.

This is the missing part of the API that will be used to reimplement failure detection of Cluster nodes.

Not sure why I set a limit to 1 million keys, there is no reason for this artificial limit, and anyway this is s a stupid limit because it is already high enough to create latency issues. So let's the users shoot on their feet because maybe they just actually know what they are doing.

The new sub-command uses the new countKeysInSlot() API and allows a cluster client to get the number of keys for a given hashslot.

Redis functions start in low case. A few functions about cluster were capitalized the wrong way.

See the top-comment for the function in this commit for details about what the function is supposed to do.

The definition of cluster size is: the number of known nodes in the cluster that are masters and serving at least an hash slot.

A §Redis Cluster node used to mark a node as failing when itself detected a failure for that node, and a single acknowledge was received about the possible failure state. The new API will be used in order to possible to require that N other nodes have a PFAIL or FAIL state for a given node for a node to set it as failing.
