Each topic is subdivided into a configurable number of partitions, which allows parallelizing a topic across multiple Kafka brokers. How Tiered Storage Works Overview of How Kafka Stores Dataĭata in Kafka is organized into topics, which are a logical equivalent to tables. Further, a FlashBlade system can be used for either or both filesystem (NFS) and object store (S3) use cases, both natively implemented on top of FlashBlade’s flash-optimized, internal database. As an S3 backend for Tiered Storage, FlashBlade provides simple, performant, reliable, and scalable storage for on-premises data pipelines. And with FlashBlade as backend, Tiered Storage has the performance to make all Kafka data accessible for both streaming consumers and historical queries.įigure 1: Kafka architecture with Tiered Storage and FlashBlade.įlashBlade’s design principles map well to disaggregated Kafka clusters both FlashBlade and Kafka use scale-out architectures with linear and predictable scaling of performance and capacity. Tiered Storage simplifies the operation and scaling of a Kafka cluster enough so that it is easy to scale individual Kafka clusters to petabytes of data. And finally, this architecture is transparent to the producers and consumers, which connect to brokers as always. Brokers now contain significantly less state locally, making them more lightweight and rebalancing operations orders of magnitude faster. The Tiered Storage architecture augments Kafka brokers with a FlashBlade object store, storing data on FlashBlade instead of local storage on brokers.

The rest of this post 1) describes how Tiered Storage and FlashBlade work together, 2) details how to set up and configure Tiered Storage, and 3) presents performance results of three realistic test scenarios. And finally, storing more data in Kafka does not help if it cannot be predictably accessed with sufficient performance.

Further, software upgrades become more challenging as rolling reboots need to be carefully staged so as not to introduce extra risk of data loss. Both impact the overall reliability of the cluster. Additionally, the use cases for Kafka as a permanent data store continue to grow.īut putting more data in a Kafka cluster results in operational challenges: more frequent node failures and longer rebalance times.
There are always more data sources to ingest and longer retention periods to increase pipeline reliability in the event of unplanned outages.
Kafka brings the advantages of microservice architectures to data engineering and data science projects. Kafka provides a cornerstone functionality for any data pipeline: the ability to reliably pass data from one service or place to another. As this feature has been in tech preview, I have been able to test the solution with an on-prem object store, FlashBlade ®. In this alternative configuration file, my output block also fails to connect to a logstash instance.This article originally appeared on and is republished with permission from the author.Ĭonfluent recently announced the general availability of Tiered Storage in the Confluent Platform 6.0 release, a new feature for managing and simplifying storage in large Kafka deployments. ERROR dial tcp :5044: connect: connection refused The same way as syntax validation (test config), you can provide a different configuration file for output connection test: ~]# filebeat test output -c /etc/filebeat/filebeat2.ymlĭial up. In this case my localhost elasticsearch is down, so filebeat throws an error saying it cannot connect to my output block. ERROR dial tcp :9200: connect: connection refused To test the output block (i.e: if you have connectivity to elasticsearch instance or kafka broker), you can do: ~]# filebeat test outputĭial up. If you want to define a different configuration file, you can do: ~]# filebeat test config -c /etc/filebeat/filebeat2.yml If you installed the RPM, it uses /etc/filebeat/filebeat.yml. If you just downloaded the tarball, it uses by default the filebeat.yml in the untared filebeat directory. To test your filebeat configuration (syntax), you can do: ~]# filebeat test config Assuming you're using filebeat 6.x (these tests were done with filebeat 6.5.0 in a CentOS 7.5 system)
