Tutorial on querying live streams of data with ksql (Kafka SQL)

Real time data querying is becoming a modern standard. Who wants to wait until the next day or week when needing to take decision now? The stream of data comes from an Apache Kafka topic which can be queried via ksqlDB. Components To keep things simple, all the pieces have been put together in a “one-click” Docker Compose project which contains: ksqlDB from the ksqlDB quickstart A Hue Editor already configured with the ksqlDB Editor One-line setup For fetching the configurations and starting everything:…

Quick checking Hue's SQL Editor connections to Databases in Kubernetes

Let's see one way to quickly check why Hue can't connect to a SQL Database in the Kubernetes world. We previously documented how to run Hue in Kubernetes or Docker. The concept is to use the Database specific command shell on the command line to try to send some queries. Apache Hive is the Data Warehouse used as example (but this would work the same with psql, mysql, …) or any other Database Hue can connect to.…

REST API for sending SQL queries and Browsing files

Hi Data App Builders, Are you looking at executing some SQL queries of Browsing S3 files programatically? (so that it can be automated for example) The Hue development flow continues to mature (Docker Quick Start, improved CI, shareable Web Components…) and is now getting more help on how to reuse its API. Concept The REST API is not properly public yet and can (will) be simplified in the current work in progress HUE-1450.…

Hue in Kubernetes

Let’s see how to automate the deployment further and run this into a container orchestration like Kubernetes.  We previously documented the Hue Docker image that provides the latest Hue web server into a “box”. Hue ships with a Helm chart to make it really easy to get started. Helm is a package manager for Kubernetes. More advanced, directly use the yaml config files. In a Shell, after installing Helm, just execute these three instructions to boot a live Hue with its database:…

Quickstart Hue in Docker and query any of your Database

Query any Data Warehouse in minutes! In this tutorial we configure Hue to use an existing MySQL database and point to an Apache Hive data warehouse that we want to query. Note If you are looking another warehouse than Hive, check out all the other connectors. There are two important concepts: Persistence: Hue needs an existing database with transactions like MySQL to support concurrent requests and also not lose the registered users, saved queries, sharing permissions… when the server gets stopped.…
