Jordan and I actually spent some time building an HTAP database at SingleStore.</p> <h2 id="the-good-old-days-80s">The good old days (&rsquo;80s) </h2> <p>Back in the &rsquo;80s, one relational database did everything. Transactions (OLTP) during the day and reports after hours (OLAP). Databases like Oracle V2 and IBM DB2 ran OLTP and OLAP on the same system; largely because data sets still fit on a few disks and compute was costly.</p>
