Kafka security via data encryption

· by Antonios Chalkiopoulos · Read in about 3 min

Secure cluster, but what happens with your data?

When it comes to security, Apache Kafka as every distributed system provides the mechanisms to transfer data securely across the components being involved. Depending on your set up this might involve different services such as Kerberos, relying on multiple TLS certificates and advanced ACL setup in brokers and Zookeeper. In many cases, with encryption features enabled, performance is also taking a penalty hit.

This presentation is by Angelos Petheriotis, senior engineer at HiveHome British Gas, at Apache Kafka meetup. Angelos presented the team’s journey to 50K msg/s from IoT Devices featuring our DM Stream-reactor connectors, how they use Kafka Connect Query Language and Landoop Web Tools. Enjoy! Streaming 4 billion Messages per day. Lessons Learned. from Angelos Petheriotis

Fast Avro Write

· by Stefan Bocutiu · Read in about 5 min

This article presents how Avro lib writes to files and how we can achieve significant performance improvements by parallelizing the write. A (JVM) library has been implemented and is available on Github fast-avro-write The reason we proceeded with this implementation was a project that required writing multiple Μillions of Avro messages from Kafka onto a star DW (data warehouse) in HIVE (HDFS). You might have heard about (or even dealt with) the challenges of working with HDFS.


Introduction

In this mini tutorial we will explore how to create a Kafka Connect Pipeline using the Kafka Development Environment (fast-data-dev) in order to move real time telemetry data into Elasticsearch and finally visualize the positions in a Kibana Tile Map by writing zero code…!

Kafka connect for FTP data

· by Antonios Chalkiopoulos · Read in about 8 min

An FTP server, together with a pair of credentials is a common pattern, on how data providers expose data as a service. In this article we are going to implement custom file transformers to efficiently load files over FTP and using Kafka Connect convert them to meaningful events in Avro format. Depending on data subscriptions we might get access to FTP locations with files updated daily , weekly or monthly. File structures might be positional, csv, json , xml or even binary.


MQTT stands for MQ Telemetry Transport. It is a lightweight messaging protocol, designed for embedded hardware, low-power or limited-network applications and microcontrollers with limited RAM and/or CPU. It is a protocol that drives the IoT expansion. On the other hand, large numbers of small devices that produce frequent readings, lead to big data and the need for analysis in both time and space domain (spatial-temporal analysis). Kafka can be the highway that connects your IoT with your backend analytics and persistence.

Apache Kafka London Meetup - by Landoop

· by Antonios Chalkiopoulos · Read in about 1 min

How to simplify your ETL process using Kafka Connect for (E) and (L). Introducing KCQL - the Kafka Connect Query Language for fast-data pipelines. Using KCQL to set up Kafka Connectors for popular in-memory and analytical systems (live demos) such as HazelCast, Redis and InfluxDB. Use fast-data-dev docker for your kafka development environment. Enhancing your existing Cloudera (Hadoop) clusters with fast-data capabilities. Demos: http://schema-registry-ui.landoop.com http://kafka-topics-ui.landoop.com http://kafka-connect-ui.landoop.com https://fast-data-dev.demo.landoop.com/ Code https://github.com/landoop/ Connectors


Time-series datastores are of particular interest these days and influxDB is a popular open source distributed time-series database. In this tutorial we will integrate Kafka with InfluxDB using Kafka Connect and implement a Scala avro message producer to test the setup. The steps we are going to follow are: Setup a docker development environment Run an InfluxDB Sink Kafka Connector Create a Kafka Avro producer in Scala (use the schema registry) Generate some messages in Kafka Finally, we will verify the data in influxDB and visualise them in Chronograph.

Coyote Testing Tool

· by Marios Andreopoulos · Read in about 7 min

A few days ago we open source’d Coyote, a tool we created in order to automate testing of our Landoop Boxes, which features a large range of environments for Big Data and Fast Data (see Kafka). Coyote does one simple thing: it takes a .yml file with a list of commands to setup, run and check their exit code and/or output. It has some other functionality too, but its essence is this.

Schema Registry UI for Kafka

· by Antonios Chalkiopoulos · Read in about 3 min

If you are looking for a safe way to interchange messages while using a fast streaming architecture such as Kafka, you need to look no further than Confluent’s schema-registry. This simple and state-less micro-service, uses the _schemas topic to hold schema versions, can run as a single-master multiple-slave architecture and supports multi data-center deployments.

We are happy to announce a UI, the schema-registry-ui a fully-featured tool for your underlying schema registry that allows visualization and exploration of registered schemas and a lot more…


We want to thank @Argos - the third largest retailer in UK - for inviting Landoop and @Accenture for hosting our presentation in one of the most beautiful theaters in the world, the IMAX theater in SCIENCE MUSEUM, London.

Ansible Nginx Let's Encrypt Automation

· by Marios Andreopoulos · Read in about 5 min

Automatic SSL certificate issuance and renew with Ansible and Let’s Encrypt Here on Landoop we prototype fast and new (sub)domains are frequently added to complement our back and front-end services. Since the beginning our specifications included “ssl everywhere”. The journey into providing fully secure and encrypted services is a long one; hence we need an adventure in the SSL land. The tools, the needs. We use ansible to manage our servers.
