Fixing boto (AWS Python interface) Quadratic Runtime Connection Pool

Background I come across some Python code using boto, the Python interface to AWS. There’s boto3, which is a newer version of boto. If you are starting a new project, you should be looking at boto3 instead of boto. I am told that boto pools connections. This is a good thing in terms of performance. Never waste HTTPS connections because it is expensive to setup. But does it limit the number of outgoing connections like SQLAlchemy’s QueuePool, or is it configurable in terms of number of pooled connections?

Migrating MySQL to Amazon RDS from Azure

I have recently migrated to Amazon RDS from MySQL on Azure VM. This percona article about migrating to RDS is actually very helpful. I have a few things to add though. Setup My setup is a self-hosted MySQL 5.6 server in VM on Azure and a new Amazon RDS for MySQL 5.6. AWS DMS I have tried AWS Database Migration Service (DMS). It is reasonably fast. The main problem is it does not look like mature technology at all.
