Oct 29, 2024 · Introduction to Presto. Presto is an open-source, distributed SQL query engine that is widely utilized for running interactive analytical queries against data sources of all sizes. Developed by Facebook for big data, its ability to handle large volumes of data efficiently makes it a powerful tool for data professionals and organizations seeking ...
With Amazon EMR release version 5.6.0 and later, you can enable SSL/TLS to help secure internal communication between Presto nodes. You do this by setting up a security configuration for in-transit encryption. For more information, see Encryption options and Use security configurations to set up cluster security in the Amazon EMR Management Guide.

Presto uses the Kerberos authentication over HTTPS on its coordinator for clients such as the Presto CLI, or the JDBC and ODBC drivers. To enable this authentication for Presto, configuration changes are made on the coordinator. No changes are required to the worker configuration as such; the worker nodes will continue to connect to the coordinator...
Presto’s Command Line Interface (CLI)can be set up to connect to a Presto coordinator that already has Kerberos authentication enabled — which is done by setting up the environment before configuring the CLI. To set up the environment for CLI Kerberos Authentication, the following have to be executed: 1. Kerberos Services — a Kerberos KDC (Key Dist...
Presto can be configured to enable frontend LDAP (Lightweight Directory Access Protocol) authentication over HTTPS for clients, such as the Presto CLI, or the JDBC and ODBC drivers. At present, only a simple LDAP authentication mechanism involving a username and password is supported. Note: Only the communication from the clients to the coordinator...
Java Keystore file for TLS Java keystore files help store authorization certificates — public key certificates with corresponding private keys — and Presto uses this file for its TLS configuration. Keys in the keystore file are generated using the keytoolkeyword. A sample keystore file setup is explained in the screenshot below. Image Source Note t...
System access control plugins enforce authorization at a global level before any connector level authorization. There are two kinds of plugins that can be used in this case: 1. Presto’s built-in plugins which can be used to implement the system access control 2. Self-developed plugins (if you prefer a little tech adventure) by following the guideli...
Presto allows room to configure secure communication between its nodes. The communication is secured with SSL/TLS and is configured in the config.propertiesfile. It is important to note that the SSL/TLS on the worker and coordinator nodes are configured using the same set of properties and while every node in the cluster must be configured, do bear...
Presto uses industry standard technologies to manage your data and secure it from unauthorized access. If you are still on the fence about deploying Presto, perhaps because you aren’t entirely sure your data is secured with it, you can be rest assured it is. From Kerberos authentication, LDAP authentication, java truststores and keystores, and buil...
Rakam is a solution that allows you to build your own analytics service using Presto. It provides an analytics infrastructure on top of your AWS account. You install rakam on your cloud provider (AWS, Google Cloud, Azure etc.) and use our API and SDK’s and we store your data in ORC format in your cloud provider and use Presto to run SQL queries on ...
Nov 16, 2023 · Presto is a cutting-edge open-source distributed SQL query engine designed for high-performance analytics on big data. It was developed by Facebook and has gained widespread adoption in the tech industry due to its speed, flexibility, and scalability. Presto allows users to analyze large datasets stored in various data sources, including Hadoop ...
Secure Internal Communication# The Presto cluster can be configured to use secured communication. Communication between Presto nodes can be secured with SSL/TLS. Internal SSL/TLS configuration# SSL/TLS is configured in the config.properties file. The SSL/TLS on the worker and coordinator nodes are configured using the same set of properties.
Aug 28, 2024 · When it comes to Presto database security, there are several best practices that can help protect your data from unauthorized access and ensure the integrity of your queries. 1. Use SSL/TLS Encryption # SSL/TLS encryption is essential for secure communication between Presto clients and servers.

Connecting through Presto REST API Endpoints. Presto on Qubole authenticates Presto REST API endpoints when SSL is enabled. The inter-node communication between the coordinator and worker nodes is authenticated only when SSL is enabled in Presto version 0.208. But in Presto version 317, the communication between the coordinator and worker nodes ...
