Hi folks,

When was the first release of Mnesia with support for disc_copies (ram + disk)?

In http://en.wikipedia.org/wiki/In-memory_database, under "Hybrids with on-disk databases", they claim that the first database engine to support both ram and disk tables did so in 2003. I remember using Mnesia with this feature year 2000.

Thank you
/Fredrik

Mnesia had this feature from the very beginning. It was present in
Erlang/OTP R1A which was released in june 1996. But Erlang/OTP did not
reach the open source community until 1998.
