How many records can PostgreSQL handle?

PostgreSQL is not natively distributed. Scalable depends on your needs. Typically \u201cdistributed\u201d means a database that can work as a group of several nodes (instances, servers, etc.) working together. Most relational databases are not built with this architecture and instead focus on being a single server installation.

Also to know is, what is the maximum database size in PostgreSQL?

The basic block size can be increased when PostgreSQL is built, up to a maximum of 32KB, thereby giving a theoretical table size limit of 64TB. Some operating systems impose a file size limit that prevent files of this size from being created, so PostgreSQL stores table data in multiple files, each 1GB in size.

Subsequently, question is, can Postgres handle big data? PostgreSQL is well known as the most advanced opensource database, and it helps you to manage your data no matter how big, small or different the dataset is, so you can use it to manage or analyze your big data, and of course, there are several ways to make this possible, e.g Apache Spark.

Keeping this in view, how many users can Postgres handle?
