title: CDC (Change Data Capture) in Google Cloud SQL
body: <p>Any way to capture data changes in a Google Cloud SQL database that can trigger external scripts, for real time data replication (e.g. Cloud SQL instance that replicates changes to a MySQL instance in an office, and viceversa).</p>
  
  <p>A poll solution would work but it wouldn't be "real time" ... if I poll the Cloud SQL instance say every 10 seconds, I would have a max latency of 9 seconds and a huge Cloud SQL invoice for 8,640 reads per day ;).</p>
  
  <p>Thanks!</p>
