Architecture of Looker
In the AWS VPC, customers can host Looker. Installing, configuring, and managing Looker apps, as well as other IT responsibilities connected to Looker applications, becomes easier when you use a Looker-hosted instance. It's worth noting that the Looker application host is separate from data storage. Data is never copied to a Looker instance and is always stored in the database.
Looker also needs an outward network connection to authorize, backup Git, relay emails, and run licensing checks.
By default, the Internal databases of the Looker application use HyperSQL as an in-memory database. The database size expands in busy situations, causing performance concerns. The HyperSQL database must be replaced with a MySQL database backend to overcome these issues.
A proxy server/load balancer connects multiple looker devices in a clustered system. HTTPS is used by each node to interact with the others, adding an extra degree of protection.
For an instance of production with a cent percent uptime, this would be the recommended approach.
What exactly is LookML?
In a SQL database, LookML is the language for describing dimensions, aggregates, data relationships, and calculations. Looker uses the LookML concept to construct SQL queries against a particular database.
Working of Looker
A Looker is a program where SQL queries are created and execute against the database. Depending on a LookML project, that explains the relationship among the tables and columns in a database, it generates SQL queries.
The following stages will describe how a Looker works:
1. Query Viewing
You can find out what looker will send the database to acquire the data by looking at the SQL tab in the data section. You may even view queries in the SQL Runner using the buttons at the bottom.
2. A Looker Query's canonical form.
All of the dimensions, explorations, metrics, and views mentioned in a formula are defined by the LookML project.
3. Using Looker's SQL Runner to run raw SQL
Looker has the SQL runner capability that allows you to execute Database connectivity using SQL you've set up. SQL Runner's raw queries of SQL generate the same set of results.
If SQL has any errors, SQL runner would highlight the SQL command's error as well as the position of the error in an error message.
