How about light-weight processes in languages like Erlang?
How/why do functional languages(specifically Erlang) scale well?
Mnesia 3.0 or later must be running on the Erlang node.
The Erlang interpreter can also be accessed
through the interface module int(3).
Erlang uses the term"process" because it does not expose
a shared-memory multiprogramming model.
The Erlang emulator keeps track of a stack trace,
information about recent function calls.
Some values of ResourceId should be avoided or Erlang/OTP will not work properly.
An example of how to compile code with debug information from the Erlang shell:.
We combine the theory of functional programming and the practice of how that works in Erlang.
To make the test fair, each new test run is to run
in its own, newly created Erlang process.
Mnesia is
a multiuser distributed DBMS specially made for industrial telecommunications applications written in Erlang, which is also the intended target language.
The applications now implemented in Erlang need a mixture of a broad range of features,
which generally are not satisfied by traditional DBMSs.
A connection could end abnormally because of an programming error in the Erlang ODBC application, but also if the ODBC driver crashes.
In Erlang, there is no interface to retrieve a mark with run/2,3,
so only the secondary purpose is relevant to the Erlang programmer.
In this module, the equivalent of the register/2 and whereis/1 BIFs(for local name
registration) are implemented, but for a network of Erlang nodes.
Sometimes the system can
enter a state where the reported memory from Erlang: memory(total)
is very different from the memory reported by the OS.
This means that a lot more information on the subject is to be found in the Erlang book or in Erlang Reference Manual.
Notice that Erlang already gives a special meaning to\ in literal strings,
so a single\ must be written as"\\" and therefore a double\ as"\\\\".
Greg Hewgill above was correct about the Erlang meaning of the word"process",
and here there's a discussion of why Erlang could do processes lightweight.
Note that Erlang already gives a special meaning to\\ in literal strings,
why a single\\ has to be written as"\\\\" and therefore a double\\ as"\\\\\\\\".

The Erlang connection process spawned by connect/2,
will open a port to a c-process that handles the communication with the database through Microsoft's ODBC API.

Mnesia is a

The rest of this section is therefore deliberately not adapted for reading by the Erlang programmer,
but the examples can help in understanding NAMES as they can be used by(*SKIP).

The Erlang port will be kept open for exit signal propagation,
if something goes wrong in the c-process and it exits we want know as mush as possible about the reason.
Errors discovered by the ODBC driver- If calls to the ODBC-driver fails due to
circumstances that can not be controlled by the Erlang ODBC application programmer,
an error string will be dug up from the driver.
