The Challenges of Delivering Hybrid Transactions/Analytical Processing


The database pendulum is in full swing. Ten years ago, web-scale companies began moving away from proprietary relational databases to handle Big Data use cases with NoSQL and Hadoop. Now, for a variety of reasons, the pendulum is swinging back toward SQL-based solutions. What many companies really want is a system that can handle all of their operational, OLTP, BI, and analytic workloads. Could such an all-in-one database exist?


This O’Reilly report, authored by Rohit Jain, CTO of Esgyn Corporation, examines this quest for database nirvana, or what Gartner recently dubbed Hybrid Transaction/Analytical Processing (HTAP). Rohit takes an in-depth look at the possibilities and the challenges for companies that long for a single query engine to rule them all.

With this report, you’ll explore:

  • The challenges of having one query engine support operational, BI, and analytical workloads
  • Efforts to produce a query engine that supports multiple storage engines
  • Attempts to support multiple data models with the same query engine
  • Why an HTAP database engine needs to provide enterprise-caliber capabilities, including high availability, security, and manageability
  • How to assess various options for meeting workload requirements with one database engine, or a combination of query and storage engines
