April 2023 Summaries

Bitemporal data is a method that allows users to update one record and query its status as it changes through time. This technique can be used in various scenarios such as employee records, options trading, and auditing. The concept of bitemporal data is based on the Asserted Versioning Framework (AVF), which operates on data in two-dimensional time. Each row in a bitemporal table is associated with two temporal intervals: effective time and asserted time. Effective time defines when the data contained in a row is valid, while asserted time is the time period in which the data in the row is true. The pg_bitemporal project is an implementation of AVF that works using PostgreSQL.

The text discusses how to save money by managing non-production services using the Aiven CLI. It explains that running these services when they're not needed can waste resources, and provides a detailed guide on how to start and stop them as needed. The author emphasizes the importance of understanding the specifics of each service type before power cycling, as some may lose data upon shutdown. They also provide an example shell script that automates this process using the Aiven CLI and jq JSON processor.

Cloud cost optimization is crucial as organizations move more workloads to the cloud, aiming to reduce infrastructure costs while maintaining high levels of uptime, security, and resiliency. Aiven provides best practices for optimizing cloud resources, including proper sizing, automating configurations, and implementing monitoring and alerting systems. Additionally, midterm strategies involve evaluating operational patterns, streamlining dev, Q&A, and production environments, and considering open source alternatives to proprietary infrastructure components. Ongoing efforts should focus on assessing cloud vendors, technology stacks, and team needs for future growth and productivity improvements.

In the first quarter of 2023, Aiven released several updates to its products and services. These include the General Availability of Aiven for Apache Flink®, a fully managed Flink SQL service that enables real-time data processing. Additionally, new organizational concepts were introduced, allowing users to manage users, authentication, and billing settings more easily. PostgreSQL® version 15 was also supported, offering improved performance and efficiency. Klaw, an open source Apache Kafka® governance tool, saw two new releases with key features such as a redesigned React UI and support for authorization from OAuth2 providers/Active Directory. The Aiven Console received a new home screen that provides quick access to projects and services, while Github authentication was added for easier sign-up and authentication. A graphical migration wizard for MySQL was introduced, making data migration simpler, and ClickHouse® integrations can now be managed directly in the Aiven Console.

Aiven has announced the general availability of its managed service for Apache Flink, enabling real-time data processing when used with Apache Kafka to create a robust event streaming infrastructure. In February, Aiven introduced a new organizational concept for managing users, authentication, and billing settings, and enhanced its PostgreSQL service with version 15, offering improved capabilities and performance. The open-source Apache Kafka governance tool, Klaw, saw new releases with features like a redesigned UI and OAuth2 support. Aiven also revamped its Console home screen for better project and service management, introduced GitHub authentication, launched a migration wizard for MySQL, and simplified ClickHouse integrations with a new graphical interface.

Aiven, an open-source data and streaming technology company, has launched three new free plans for its cloud services: Aiven for PostgreSQL, Aiven for MySQL, and Aiven for Redis. These free plans are available across nine AWS regions globally with specifications including a single node, 1 CPU, 1GB RAM, and 5GB storage. The free plans come with many of the platform's features such as dedicated instances, data encryption, backups, and monitoring. Users can easily upgrade their free plan to a larger paid plan or move to different cloud providers like Google Cloud, Microsoft Azure, and Digital Ocean. A community forum has also been launched for developers to collaborate on applications built with open-source data technologies.

Aiven has announced that its full portfolio of open source data infrastructure services is now available on AWS Marketplace, allowing customers to purchase Apache Kafka as a fully managed service from Aiven and access the complete Aiven portfolio via self-service. This integration simplifies usage and consumption of Aiven's services for existing AWS customers. The comprehensive availability of Aiven’s services in AWS Marketplace provides simple access and centralized billing, allowing customers to leverage their existing commitments with AWS to expand their tech stack with Aiven open source services.

Aiven has released version 4.0.0 of the Aiven Terraform Provider, which includes significant changes to make managing data infrastructure easier using Terraform. The new release marks a shift from the older Terraform Plugin SDKv2 to the new Terraform Plugin Framework, providing better type checking. In this update, schema fields now use strict types instead of strings, and auto-upgrading functionality has been added for existing Terraform state files. Some deprecations have also been introduced, such as ip_filter and namespaces (for M3DB), which will be replaced in the upcoming version 5.X. The latest Aiven Terraform Provider is now compatible with Protocol Version 6, allowing for long-term stability and a faster bug fix cycle.

During Women's History Month in March, Aiven celebrated the contributions of women within their company by sharing inspiring stories on LinkedIn. The company also sponsored FemTechConf, a community-driven organization that empowers women and gender non-conforming individuals in tech. Aiven is dedicated to creating an inclusive and safe environment for all employees through initiatives like Lift, one of their Employee Resource Groups focused on supporting and encouraging women at the company.
