Is ObjectDB scalable? What are its limitations?

ObjectDB is highly scalable and can manage efficiently databases in a wide range of sizes, from a few Kilobytes to hundreds of Gigabytes and even Terabytes. ObjectDB can be used in small embedded single user applications as well as in heavy loaded multi threaded multi user applications.

ObjectDB supports:

  • Database file size up to 128 TB (= 131,072 GB = 134,217,728 MB).
  • Up to 2,147,483,648 entity classes per database file.
  • Up to 2,147,483,648 indexes per database file.

ObjectDB is very easy to use. Follow the Getting Started Tutorial and the Quick Tour manual chapter and in minutes you may be able to write and run first Java programs against ObjectDB.

Prior knowledge or experience in database programming (SQL, JDBC, ORM, JPA, etc.) is not required, but some background in using the Java language is essential.
