I am having a client node and a data node. i am using the client node to communicate to data node. My question is when i perform an insertion from client node does the program control returns to client node once the information is sent to data node over the network or is it blocked till the data is inserted and indexed on the data node.
Please help me.

If you are using the java API the answer is maybe, it depends on how you use it. In addition, even if you use the synchronous API you have to wait for a refresh for you data to be searchable. By default they happen every second.

Good question and it's worth a few links 🙂 This link might be helpful,
look at async replication and refresh

At this point you'll be confused between refresh and flush, then read this
