title: Alternative to a large database
body: <p>I am having a database with tables having billions of rows in a single table for a month and I am having data for the past 5 years. I tried to optimize the data in all possible ways, but the latency is not decreasing. I know there are some solutions like using horizantal shrading and vertical shrading. But I am not sure about any open source implementations and the development time required to make the switch. Does anyone have any experience with using such systems?</p>
  
  <p>Thank you.</p>
