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 ie. Scala and Kotlin.

Technology
[edit]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. There is a resemblance between Java streams and SQL which is exemplified in the following table[11]
| 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
[edit]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[12]. It also includes an in-JVM-memory data store.
Speedment, Inc.
[edit]Speedment was founded by the serial-entrepreneurs Carina Dreifeldt[13] (CEO) and Per Minborg [14](CTO) in 2010. It is a spin-off from the music service Chilirec[4].
Speedment, Inc. is headquartered in Palo Alto, CA, USA in Silicon Valley.
