* [sql lab] a better approach at limiting queries Currently there are two mechanisms that we use to enforce the row limiting constraints, depending on the database engine: 1. use dbapi's `cursor.fetchmany()` 2. wrap the SQL into a limiting subquery Method 1 isn't great as it can result in the database server storing larger than required result sets in memory expecting another fetch command while we know we don't need that. Method 2 has a positive side of working with all database engines, whether they use LIMIT, ROWNUM, TOP or whatever else since sqlalchemy does the work as specified for the dialect. On the downside though the query optimizer might not be able to optimize this as much as an approach that doesn't use a subquery. Since most modern DBs use the LIMIT syntax, this adds a regex approach to modify the query and force a LIMIT clause without using a subquery for the database that support this syntax and uses method 2 for all others. * Fixing build * Fix lint * Added more tests * Fix tests |

Apache Superset
Apache Superset is a data exploration and visualization web application.
Superset provides:
- An intuitive interface to explore and visualize datasets, and create interactive dashboards.
- A wide array of beautiful visualizations to showcase your data.
- Easy, code-free, user flows to drill down and slice and dice the data underlying exposed dashboards. The dashboards and charts acts as a starting point for deeper analysis.
- A state of the art SQL editor/IDE exposing a rich metadata browser, and an easy workflow to create visualizations out of any result set.
- An extensible, high granularity security model allowing intricate rules on who can access which product features and datasets. Integration with major authentication backends (database, OpenID, LDAP, OAuth, REMOTE_USER, ...)
- A lightweight semantic layer, allowing to control how data sources are exposed to the user by defining dimensions and metrics
- Out of the box support for most SQL-speaking databases
- Deep integration with Druid allows for Superset to stay blazing fast while slicing and dicing large, realtime datasets
- Fast loading dashboards with configurable caching
Database Support
Superset speaks many SQL dialects through SQLAlchemy, a Python ORM that is compatible with most common databases.
Superset can be used to visualize data out of most databases:
- MySQL
- Postgres
- Vertica
- Oracle
- Microsoft SQL Server
- SQLite
- Greenplum
- Firebird
- MariaDB
- Sybase
- IBM DB2
- Exasol
- MonetDB
- Snowflake
- Redshift
- more! look for the availability of a SQLAlchemy dialect for your database to find out whether it will work with Superset
Druid!
On top of having the ability to query your relational databases, Superset ships with deep integration with Druid (a real time distributed column-store). When querying Druid, Superset can query humongous amounts of data on top of real time dataset. Note that Superset does not require Druid in any way to function, it's simply another database backend that it can query.
Here's a description of Druid from the http://druid.io website:
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.
