title: Apache Arrow R - is there a use case when data is stored in a database
body: <p>I have all of my data in a Microsoft SQL database and i'm using R</p>
  <p>From reading docs it looks like the main use case for Arrow is having the data as parquet files (unless the DB backend is Arrow-flight enabled)</p>
  <p>Are there benefits to using Apache Arrow in my case?
  should i expect e.g. faster processing because of SIMD?
  or lower memory usage of the data stored in memory?</p>
