* Created migration to fix the bug * Working also on MySQL * Added support for Vertica Grains (#515) * Fix #529 1 "This Session's transaction has been rolled back" (#530) * Fixing the specific issue * Added an additional fix for a similar error in #529 Background: - When an object is modified by SQLAlchemy, it is invalidated so need to be fetched again from the DB - If there's an exception during a transaction, SQLAlchemy performs a rollback and mark the connection as dirty. Bug: - When handling exceptions, the exception handler tries to access the name of the cluster in the main object. Since the name has been invalidated due to a write, SQLAlchemy tries to fetch it on a 'dirty' connection and spits out an error. Solution: - Fetch the information for handling the exception before starting the process. * Modified the migration function to to automatically detect the the foreign keys based on the signature. It supports also sqlite using batch migrations * i18n: Fix typo in Druid cluster broker port label (#512) * Update models.py (#541) removing duplicated `user_id` def |

Caravel
Caravel is a data exploration platform designed to be visual, intuitive and interactive.

Caravel
Caravel's main goal is to make it easy to slice, dice and visualize data. It empowers users to perform analytics at the speed of thought.
Caravel provides:
- A quick way to intuitively visualize datasets by allowing users to create and share interactive dashboards
- A rich set of visualizations to analyze your data, as well as a flexible way to extend the capabilities
- An extensible, high granularity security model allowing intricate rules on who can access which features, and integration with major authentication providers (database, OpenID, LDAP, OAuth & REMOTE_USER through Flask AppBuiler)
- A simple semantic layer, allowing to control how data sources are displayed in the UI, by defining which fields should show up in which dropdown and which aggregation and function (metrics) are made available to the user
- Deep integration with Druid allows for Caravel to stay blazing fast while slicing and dicing large, realtime datasets
Database Support
Caravel was originally designed on top of Druid.io, but quickly broadened its scope to support other databases through the use of SQLAlchemy, a Python ORM that is compatible with most common databases.
What is Druid?
From their website at http://druid.io
Druid is an open-source analytics data store designed for business intelligence (OLAP) queries on event data. Druid provides low latency (real-time) data ingestion, flexible data exploration, and fast data aggregation. Existing Druid deployments have scaled to trillions of events and petabytes of data. Druid is best used to power analytic dashboards and applications.

Tip of the Hat
Caravel would not be possible without these great frameworks / libs
- Flask App Builder - Allowing us to focus on building the app quickly while getting the foundation for free
- The Flask ecosystem - Simply amazing. So much Plug, easy play.
- NVD3 - One of the best charting libraries out there
- Much more, check out the
install_requiressection in the setup.py file!
