As the adoption of Kubernetes (K8s) continues to rise, the necessity for efficient management tools for software running on this platform also increases. For users of Aerospike on Kubernetes, this need is addressed by the Aerospike Kubernetes Operator Control (akoctl) tool. This command-line utility offers simplified and streamlined interactions with the Aerospike Kubernetes Operator, providing essential functions that ease the day-to-day operations of Aerospike clusters within a Kubernetes environment.

Like a well-prepared community bracing for the impact of a natural disaster, databases must be equipped to face unforeseen challenges. In the world of databases, few things are as dreaded as running out of memory, a situation referred to as OOM. Enter Aerospike's savior: the stop-writes condition, a protective measure designed to avert the nightmarish scenario of OOM. It acts as a vigilant sentinel, ensuring your database stays far from the brink of unrecoverable states. Think of it as your emergency go-bag or the life vest under your seat, offering respite when you need it most, though you hope never to use it.

Aerospike is renowned as a very fast, very scalable database capable of storing billions or trillions of records, as well as being able to replicate the data to multipe remote database clusters. Hence, a common question which arises is: "How can I validate that two clusters are in sync?". This used to be a difficult problem, but new API calls in Aerospike v5.6 make this task substantially easier. In this blog we will look at one of these new API calls and use it to develop some code to show how a cluster comparator could be written.

Aerospike is known for incredible speed and scalability. As a bonus, people using Aerospike often recognize a far lower Total Cost of Ownership (TCO) compared with other technologies. Optimizing the distribution of data between servers contributes to this low TCO and Aerospike's uniform balance feature allows for almost-perfect even distribution of data across the servers, resulting in better resource utilization and easier capacity planning. This blog post examines how this feature works.

This article describes how queries in Aerospike allow applications to process query results as a stream of records, paginate over results, partition a query for parallelism, and resume execution at a later time.

While it is possible to process a data set using a large number of parallel streams, a higher degree of parallelism may not be necessarily optimal or even possible. This article explores how to think about parallelism, and discusses many bottlenecks that limit the level of parallelism. It also highlights the need to perform measurements in the target setup due to many factors that cannot be easily quantified.

Aerospike provides several mechanisms for accessing large data sets over parallel streams to match worker throughput in parallel computations. This article explains the key mechanisms, and describes specific schemes for defining data splits and a framework for testing them.

The REST Gateway provides you with a well known interface to your Aerospike Database, and a Swiss army knife-like solution to a variety of architectural problems where you might not want to integrate a full fledged Aerospike client into every application.

Aerospike Database is deployed by large-scale real-time applications in a wide range of verticals. Businesses need “as it happens” visibility over these systems - sometimes in near-real time - via notifications, ad-hoc queries, dashboards, and reports.

SQL is broadly used as a data access language for analytics, and Trino provides a powerful engine for SQL access to multiple data sources. Aerospike Trino Connector enables SQL access to Aerospike data through Trino, and more broadly, allows Aerospike to be used to expand fast analytics data accessible from Trino.
