What is the Initiator Node?

Post by piglet » Fri Jan 18, 2013 2:24 pm

Hi guys,

How do I determine which node in a cluster that is considered to be the "initiator node"? And what exactly is the "initiator node" for that matter?

Thank you

In the context of a client connection, the initiator node is the node associated with the specific host to which the connection was made. The initiator node can, and usually does, also function as an executor node.

Thanks jpcavanaugh !

So basically its what ever node I connect to and then do something, i.e. run a query. Cool. For some reason I was thinking there was a "main" node of sorts. :oops:

Thats one of the best parts of vertica - there is no main node or leader node - all nodes are equal.
