#606 Refactor and enhance pipeline with batch processing Pull request opened by zhuoyuan-liu This update introduces a new batch processing mechanism for node last seen time udpate, improving efficiency and reducing redundant operations. It also removed unused functions. Discontinued historical tracking of IP addresses and node names, as there are no clear use cases for this data. What is missing in this PR: • Graceful Shutdown for the Main Function: The main function needs to be updated to allow graceful shutdown to ensure cached data is properly flushed before shutdown. jmpsec/osctrl
