title: BigQuery maximum row size
body: <p>Recently we've started to get errors about "Row larger than the maximum allowed size".</p>
  
  <p>Although documentation states that limitation in 2MB from JSON, we have successfully loaded 4MB (and larger) records also (see job job_Xr8vR3Fyp6rlH4zYaZFbZSyQsyI for an example of a 4.6MB record).</p>
  
  <p>Has there been any change in the maximum allowed row size? 
  Erroneous job is job_qt_sCwokO2PWKNZsGNx6mK3cCWs. Unfortunately the error messages produced doesn't specify what record(s) is the problematic one.</p>
