Athena vs Redshift Spectrum : <p>I am kind of evaluating Athena &amp; Redshift Spectrum. Both serve the same purpose, Spectrum needs a Redshift cluster in place whereas Athena is pure serverless. Athena uses Presto and Spectrum uses its Redshift's engine</p>

<p>Are there any specific disadvantages for Athena or Redshift spectrum?
Any limitations on using Athena or Spectrum ?</p>
