Kafka MirrorMaker - Capabilities and Limitations

Discover the capabilities and limitations of Public Cloud Databases for Kafka MirrorMaker

Last updated January 19th, 2023

Objective

This page provides the technical capabilities and limitations of the Public Cloud Databases for Kafka MirrorMaker offer.

We continuously improve our offers. You can follow and submit ideas to add to our roadmap at https://github.com/ovh/public-cloud-roadmap/projects/2.

Capabilities and limitations

Supported regions and multi-AZ

The Public Cloud Databases offer is available in the following regions:

  • BHS (Beauharnois, Canada)
  • DE (Frankfurt, Germany)
  • GRA (Gravelines, France)
  • SBG (Strasbourg, France)
  • UK (London, United Kingdom)
  • WAW (Warsaw, Poland)

Kafka MirrorMaker nodes have to be in the same region. Multi-AZ is currently not supported.

Kafka versions

The Public Cloud Databases offer supports the following Kafka versions:

  • Kafka MirrorMaker 2.0

You can follow Kafka Release Cycle on their official page : https://kafka.apache.org/downloads

Kafka clients

You can use any of the Kafka-recommended clients to access your cluster.

Please note that Kafka Connect is not available so far.

Plans

Three plans are available:

  • Essential
  • Business
  • Enterprise

Here is an overview of the various plans' capabilities:

Plan Number of nodes by default Additional nodes
Essential 1 No
Business 3 No
Enterprise 6 No

Your choice of plan affects the number of nodes your cluster can run as well as the SLA.

Nodes

  • Essential: The cluster is delivered with 3 nodes by default.
  • Business: The cluster is delivered with 3 nodes by default.
  • Enterprise: The cluster is delivered with 6 nodes by default.

License type

Kafka software is under the Apache 2 license, a liberal open-source license. More information on https://github.com/apache/kafka/blob/trunk/LICENSE.

Hardware resources

Here are the node types you can choose from:

Essential plans

Name Disk (GB) Cores Memory (GB)
db1-7 N/A 2 7
db1-15 N/A 4 15
db1-30 N/A 8 30

Business plans

Name Disk (GB) Cores Memory (GB)
db1-7 N/A 2 7
db1-15 N/A 4 15
db1-30 N/A 8 30

Enterprise plans

Name Disk (GB) Cores Memory (GB)
db1-7 N/A 2 7
db1-15 N/A 4 15
db1-30 N/A 8 30

Right now, all nodes of a given cluster should be of the same type and distributed in the same region.

Features

Network

Public as well as private networking (vRack) can be used for all the offers.

Ingress and Egress traffic are included in the service plans and unmetered.

Private network considerations

Here are some considerations to take into account when using private network:

  • Network ports are created in the private network of your choice. Thus, further operations on that network might be restricted - e.g. you won’t be able to delete the network if you didn’t stop the Public Cloud Databases services first.
  • When connecting from outside subnet, Openstack IP gateway must be enabled in the subnet use for the Database service. The customer is responsible for any other custom network setup.

Kafka replication and data retention

You can select a Kafka source cluster and a Kafka destination cluster from the same Public Cloud project. External Kafka clusters are not supported so far.

You need at least 2 Kafka clusters to create replication flows.

Replication flows allowed parameters are:

  • Source
  • Target
  • Topics
  • Topics exclusion
  • Sync group offset
  • Sync interval in seconds (s)
  • Heartbeats (true/false)

Data retention is only limited by your cluster storage space.

Advanced parameters

We do not currently support Kafka advanced parameters.

Backups

Kafka is a streaming tool. We don't backup Kafka data.

Logs and metrics

Logs and metrics are available via the OVHcloud Public Cloud Control Panel. As of today, you can't export logs and metrics, nor plug them into a remote tool.

  • Logs retention: 1000 lines of logs
  • Metrics retention: 1 calendar month

Please note that if the database instance is deleted, logs and metrics are also automatically deleted.
