EBS volume

Useful for t2.micro and other instances with no access to instance store. Use this if you prefer not to mess with the root volume.

1. Create the EBS volume e.g., 1 GB.

Flask-SQLAlchemy Caching

The following gist is an extract of the article Flask-SQLAlchemy Caching. It allows automated simple cache query and invalidation of cache relations through event among other features.

Usage

retrieve one object

# pulling one User object

user = User.query.get(1)

# The following adds delete, insert, and update events after successful commits.
# SQLAlchemy provides only events after flushes, but not after commits.
# The classes are adapted from Flask-SQLAlchemy.
