Speedment is a Java stream ORM developed by the team at Speedment, Inc. It is an open source tool hosted at Github[1] that uses Java 8 streams[2] to develop relational database applications. Speedment is available under the Apache 2-license. Speedment also licenses extensions under closed-source commercial terms.[3] Speedment is implemented in Java and accessible from software written in other languages that works on the JVM i.e. Scala and Kotlin.

Technology
Speedment is a Java 8 Stream ORM Toolkit and Runtime.[10] The toolkit analyzes the metadata of an existing legacy relational database and creates a Java representation of the data model which together with the Speedment runtime allows the user to create Java applications using Java 8 streams without any specific query language or API.[11] There is a resemblance between Java streams and SQL which is exemplified in the following table[12]
SQL | Java 8 Stream Equivalent |
---|---|
FROM |
stream() |
SELECT |
map() |
WHERE |
filter() (before collecting) |
HAVING |
filter() (after collecting) |
JOIN |
flatMap() |
DISTINCT |
distinct() |
UNION |
concat(s0, s1).distinct() |
ORDER BY |
sorted() |
OFFSET |
skip() |
LIMIT |
limit() |
GROUP BY |
collect(groupingBy()) |
COUNT |
count() |
Licensing and edition
Speedment is available as an open source and an enterprise edition. The open source edition is limited to open source databases. The enterprise edition, which requires a proprietary license, adds on commercial databases (Oracle, DB2, DB2/400 and Microsoft SQL Server) as well as Avro-files.[13] It also includes an in-JVM-memory data store.
