This is not an ideal solution for a system that needs to process distributed transactions (i.e. However, all of these systems can be considered “half-distributed” in the sense that they’re able to distribute reads across machines in a cluster, but depend on a single write node which creates a write bottleneck. Managed PostgreSQL is provided by all the major cloud providers – AWS RDS for PostgreSQL, Google Cloud SQL for PostgreSQL or Azure Database for PostgreSQL – among others. Some organizations try to overcome the management challenges of distributed database instances by using a managed PostgreSQL solution. ![]() Plus, you aren’t able to control data residency which can become an important factor when running a distributed system and adhering to various financial service compliance regulations. As discussed above, setting up and managing disparate PostgreSQL instances in several locations is not the ideal solution. You either have a global customer base now, or you likely want to. Distributed architecture for truly distributed transactions Instead, they have switched to distributed SQL databases, which offer built-in horizontal scalability and replication. And, for a more fault tolerant system, you will need to set up replication.Ī sharded system limits your development speed which creates additional costs, wastes developer hours, and introduces risk to the business.Ĭompanies that truly understand the overhead and opportunity costs of manual sharding - both fintechs and large multinational banks - have given up on this slow and painstaking methodology. However, everywhere you set up a new database instance will require ongoing maintenance such as changing your schema or taking the database offline for upgrades. You don’t want your development team to have to manually shard the database to help it achieve scale.Ĭonceptually, sharding PostgreSQL may seem simple. If you are building an application such as a payment system that will be processing hundreds of thousands of transactions per second, you should prepare for scale. One of the well known limitations of PostgreSQL is its lack of support for horizontal (out, not up) scaling. Horizontal scale for transactions per second In this post, we are going to look at when PostgreSQL may no longer be suited for your financial service applications and business needs. This is also why it’s often used in financial services and for use cases that handle money. ![]() It’s a good fit for business critical workloads because PostgreSQL delivers a highly stable foundation and is ACID compliant. Even today it’s the fourth most popular database in the world, backed by a global community of dedicated supporters. PostgreSQL has more than 35 years of active development under its belt making it one of the most powerful and reliable relational database management systems (RDBMS).
