Using Apache Tez to Speed Up Hadoop Query Execution

Apache Tez has revolutionised how Hadoop processes queries. Its ability to optimise execution workflows, reduce latency, and improve query performance makes it a preferred choice over traditional MapReduce. As data science evolves, professionals with expertise in Tez and other big data tools will have a competitive edge. If you want to enhance your skills, enrolling in a data scientist course in Pune can help you gain in-depth knowledge and practical experience in this domain.<br>
