Iam able to send only one block of data.How to send multiple blocks of data by injecting only once and rest of the time message comes after delay as per the minute_index of the file.I am a noob
You want to look at the split node, it will take an array an turn it into a stream of messages.
It is a core Node-RED node so should already be in palette
Can be paired with the join node to reassemble the array afterwards if needed
Welcome to the board.
You can inject to a function node, break it to separate messages, add the required msg.delay property to each (in ms) and send them all through a delay node.
You need to use a combination of SET and UPDATE:
- SET to define the initial value of your array;
- UPDATE to modify your array (add one element in your case)
Note: SET is not mandatory.
Note 2: I used a different node palette.

I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
It might not answer your immediate question but it will help you understand the other suggestions here.
