bind and connect for primary and secondary node

GCh

Hi Bernardo,

I have a question regarding this, what does LiteSync understand under "bind" and "connect"? As far as I understand it, when I e.g. use "bind" in the context of primary node this means I "reserve" the given ip address and port number to be used by LiteSync's primary node. Consequently when I use "connect" in the context of secondary node(s), it means that it/ they connect to the ip of the primary node. I was also wondering whats the difference, in the context of LiteSync, when the primary node connects via "connect" to the secondary nodes that "bind" their ip addresses?

Thank you in advance for your answer.

Best regards,
Greg

Hi Greg,

It is the same meaning as any TCP communication. We can choose which nodes will bind to a local address (including TCP port) so other node(s) can connect to it.

It is more common to have the primary node accepting connections from secondary nodes, because in this case we need to take care of router and firewall for just a single device. But it is also possible to have the primary node connecting to the secondary nodes. In this case it needs to know the address of the secondary nodes in advance.

Note that these configurations do not affect the role of each node. The primary node will be the one that will decide the order of transactions.
