This post covers Greengage DB cluster shrink using ggrebalance: utility architecture, the FSM approach, safe data redistribution via INSERT, comparison with CTAS, rollback support, and performance test results.

Let's discuss the main changes in Greengage DB 6.30.1 product release and other updates

In this article, we will share some details of working on new Greengage features such as shrink and expand, improved foreign tables inserts, and developing Apache Iceberg integration (Greengage-to-Iceberg connector).

In this article, we consider some application scenarios to be taken into account when implementing the backup system for a Greengage DB cluster

In this article, we discuss how you can participate in the development of the Greengage DB project and become a part of the community

In this article, we describe how we developed and tested a lock-free approach as a part of the major work of implementing orphaned files removal feature. Take a peek inside our development team’s process while evaluating this feature

In this article, we talk about how we solved the problem of deleting orphaned files — data files that are not associated with any tables in a database, but may remain on the file system after a backend process crash

Now, we are also creating video articles as one more way to share information with Greengage DB users

In this article, we discuss an approach to data backup and restore in a distributed system, using Greengage DB as an example

Let's discuss the update of the documentation for Greengage DB version 6, and also briefly talk about the process of creating the Greengage DB documentation and our further plans for its development

In this article, we consider approaches to cluster scaling in Greengage DB and define the base requirements to the utilities that are currently in development

The first versions of Greengage DB are available to users

In this article, we will talk about why we decided to move the Orca query planner from the core of Greengage Database (based on Greenplum) to an extension and how we implemented it

This article is a continuation of the comparison of Greenplum with Citus. Here, we discuss data distribution and cluster balancing

With this article, we open a series of materials dedicated to a comparative review of distributed DBMS technologies. Let’s start with a comparison of Greenplum with Citus

We're happy to announce the start of the Greengage DB project
