Deploying Kafka Streams and KSQL with Gradle - Confluent.
During this instructor-led, hands-on course, you will learn how to use Confluent KSQL to transform, enrich, filter and aggregate streams of real-time data using a SQL-like language. You will also learn how to use the Apache Kafka Streams library to build streaming applications. Furthermore, you will learn how to test, monitor, secure and scale those streaming applications. You will learn how.
The join result is a new KTable representing changelog stream of the join operation. In the following example, we will perform an inner join between two KTables. The result will be an updating.
Few things to note here: first, when creating the stream we need to specify from which kafka topic the stream will be reading and the format of the records, avro in our case. Second, unlike a regular select query executed in a relational database where the results are returned once the operation finishes, a select in KSQL will keep running until interrupted, showing the results as they come.
I recently created and published a tiny but handy project which provides a few custom user-defined functions (UDFs) to work with emojis in ksqlDB.While there is a minimum viable amount of project documentation, it's often much easier based on a little application to quickly understand how to make use of these functions and what you can build with them.
For more information, see Install ksqlDB in the ksqlDB Standalone documentation. ksqlDB for Confluent Platform This is a commercial component of Confluent Platform. ksqlDB for Confluent Platform includes enterprise features, like role-based access control, and is available in Confluent Cloud.
PoC: Using KSQL to enrich Zeek logs with Osquery and Sysmon data In incident response, time is precious and something you can never get back. Typically, when I receive a security alert about an endpoint, it requires manual lookups on multiple data sources for critical pieces of information. These manual lookups can be time-consuming, create fatigue, and don’t use the power of technology to.
KSQL—the open source SQL streaming engine for Apache Kafka—makes it possible to build stream processing applications at scale, written using a familiar SQL interface. Have you ever thought that you needed to be a programmer to do stream processing and build streaming data pipelines? Think again. Apache Kafka is a distributed, scalable, and fault-tolerant streaming platform that provides.
