PrestoDB Review and Overview
The database is a repository of data and is used widely in every organization, business, and company. You search the database through firing a query and get your answers within minutes. Presto software helps in putting up these search queries in an efficient manner.
Working
It queries the database of any size ranging from gigabytes to petabytes. It allows you to perform analytics around your entire organization. The response time of Presto ranges from milliseconds to minutes. It provides you with a free solution but fast analytics solution. It runs on a collection of machines. There is a coordinator machine, and the rest of the machines are called the worker machines. The query comes from a client to the coordinator. It is the job of the coordinator to analyze the query, plan its execution, and finally distribute the tasks among the workers. After deploying the Presto software, the queries are put up through the command-line interface.
Security
You can use the Kerberos Authentication over the HTTPS for clients through the Presto coordinator. In this authentication procedure, the changes are made to the coordinator but not on the workers. It uses the Java cryptography mechanism. You can also get the LDAP Authentication, which includes the username and password technique. You can provide the security between the nodes of the Presto architecture with the help of SSL/ TLS.
Administration
Presto monitors and manages the queries through a web interface. This interface can be accessed by the coordinator with the help of an HTTP port number that is mentioned in the configuration properties of a coordinator. The main page of this interface contains the details like the query ID, username, its source, etc. At the top of the page, the listing of the currently running queries will be present. The recently completed and the failed queries will be mentioned below the currently running queries. The administrators have the power to add session properties in case they want to control the subsets of their workload.
