Cassandra Database
Health Checks

Get your Apache Cassandra nodes audited by highly skilled database professionals!

Quick Intro to Cassandra Health Checks

Our database experts will analyse your Cassandra cluster with their experience and knowledge to find both existing and future problems. Our areas of interests include resource consumption, the Java VM, the Garbage Collector, configuration, cluster topology & replication factors, schema design & compaction strategies, slow queries & consistency levels.

When a Database Health Check Can Help

A database is the heart of your application, and you want it to work well. Without a proper health check, it may start to invisibly lead you to money and / or reputation losses. A thorough examination will cost much less.

Why is your database so slow?

We will find slowdowns and will scientifically investigate them to find the root causes. Then we will explain to you what to do to speed up your database.

Why can't your database 'just scale'?

Databases are complex multi-purpose technologies. Scaling is possible but it may require specific knowledge of database internals.

Why does your database demonstrate strange behavior?

Database problems can be complicated and counterintuitive. It might be hard to understand what exactly went wrong without the years of experience we have.

Are your queries and your schema well optimised?

Trying to scale a cluster is often useless when SQL queries and the schema are not optimised. We’ll find the slowest queries, and the queries that slow down your servers. Sometimes the only problem of a slow application is missing or poorly designed indexes.

Why is your database consuming so many resources?

In many cases, you can spend less on IT infrastructure by using less nodes with more optimal schema and queries. We can get you there!

What if I want to replace my database technology?

We can help you to weigh the pros and cons, and find out if you just need to optimise your current database, because migrations are expensive.

Supported Technologies

Vettabase professionals use open source tools trusted and recommended by experts developing databases for decades. If a technology is spoken about, chances are that we have worked with it, too. We decide on a toolkit with automation at heart.

Database Health Check: Process Description

To maximize the value of our database health checks, we follow a standardized procedure that proved to be efficient throughout the years. Below you will find the description of its stages and understand what to expect from each of them. Basically, our database health check takes three working days.


Intro Call

At our intro calls, we usually ask if there are any specific cases or issues to investigate. Tell us more!


Monitoring-based check

We will examine metrics from your existing monitoring systems and setup more advanced open source monitoring solutions if required.


Schema Check

We will check your existing database schemas to see the logical and physical structure of your data and propose changes.


Server Check

We will take a look at your server configurations and see whether they can be tuned for your database to function better.


Health Check Results

You will get a detailed report with your database health check results split into several sections, and recommendations.


Explanatory Call

You will get a call from a Vettabase consultant to discuss the report, our recommendations and actions to be taken.

Marco Visibelli

At Currencies Direct, Federico Razzoli reviewed our Cassandra infrastructure, providing us with precious recommendations on how to improve its configuration and our data models. His consulting clarified the intricacies of a distributed database and the Java Virtual Machine, and allowed us to take advantage of the peculiarities of Cassandra.
I would recommend Federico to other companies to handle their database problems.
