CockroachDB stores all system data in this way too. This covers all data belonging to users like tables, indexes, etc.

This would allow users of CockroachDB to do most of the tasks using the open-source license model. However, it made a change to this in 2019.Ĭockroach Labs now offers CockroachDB under a BSL (Business Source License). The company had first offered it as open-source software. Survivability was a key requirement.Ĭockroach Labs launched CockroachDB in 2015. These developers wanted this database to spread itself naturally across availability zones. Their plan involved building a database without external dependencies. They wanted to build a database that will be composed of symmetric nodes. However, the developers also reviewed other popular databases like MySQL, PostgreSQL, Cassandra, and AWS SimpleDB. F1: A fault-tolerant distributed RDBMS that supported the ad business of Google.Spanner: A globally distributed database.They got the inspiration to build CockroachDB after reviewing database products built by Google. Spencer Kimball, Peter Mattis, and Ben Darnell founded Cockroach Labs in 2015, and this company built CockroachDB. This open-source RDBMS (Relational Database Management System) scales horizontally. It’s built to support transaction processing systems, SoRs (Systems of Record), etc. It utilizes a strongly consistent key-value store. CockroachDB focuses on consistency for this. This ability to survive is the reason why the developers of this database chose the name “CockroachDB”.ĬockroachDB focuses on maintaining data integrity even if a database operation fails. CockroachDB can survive failures of the disk, machine, rack, and data centers. CockroachDB keeps your data safe even if one database server fails. Its distributed design ensures data redundancy.
What is CockroachDB?ĬockroachDB is a distributed SQL database.
You want an RDBMS solution that focuses on these value propositions over everything else. You need a database that maintains data integrity.
It should have sufficient data redundancy.įurthermore, you don’t want corrupted data in your RDBMS even if a database solution fails. The RDBMS will secure your data even if one server fails. You want a differentiated RDBMS solution that offers survivability and data integrity as its main value proposition. Developers and data modelers know that it’s one of the most advanced RDBMS solutions. E.g., PostgreSQL supports complex SQL queries very well. However, they enjoy more popularity due to their functional capabilities. When talking about popular RDBMS solutions, you will probably first think of MySQL, PostgreSQL, etc. You can’t afford to lose data even if there’s a failure in a database server. We also assume that this system will have high visibility. Let’s assume that you want to build an important OLTP (Online Transaction Processing) or analytics system. Finally, we compare CockroachDB with some of the popular databases. In this article, we review CockroachDB and its features. This relatively new RDBMS offers a high degree of survivability to your data. This is where CockroachDB becomes important. However, do you want an assurance that your data in an RDBMS will survive even large-scale failures in application systems and servers? This narrows the choice. You can choose one from several popular RDBMSs. If you are developing a heavy-duty transaction processing system or a high-demand analytics system, you will likely use an RDBMS (Relational Database Management System). You need to choose the right database for your project.

If you are an entrepreneur or an enterprise IT leader, then you need to plan the technology stack for your software development project.
