Category:MySQL Server: Federated storage engine Severity:S4 (Feature request)
Version:5.0, 5.1, 6.0 OS:Any
Assigned to: Georgi Kodinov
Triage: D1 (Critical)

Description:
Currently the federated engine is loaded when the server is started.
It can be disabled on startup with the --skip-federated server command line option.
I would like to have it not loaded by default. 
In this case it can be re-enabled at startup by the --federated server command line option.

How to repeat:
make sure federated is compiled.
start the server.
make sure federated is available (but it should not be) in INFORMATION_SCHEMA.engines if it's compiled in.

Suggested fix:
Change the server code so that federated is not activated by default (even if the storage engine is compiled in) unless specifically enabled with the --federated server command line option.

The FEDERATED storage engine now is disabled by default in binary
distributions. The engine is still available and can be enabled by
starting the server with the --federated option.

Setting report to Need Doc Info pending push of fix into 6.0.x.

Correction: See Bug#38483: FEDERATED was not disabled in the server itself in 5.0; it's set to disabled only in the my.cnf files shipped with distributions.
[1 Aug 2008 16:35] Paul Dubois
Noted in 5.0.64 changelog.

The FEDERATED storage engine is now disabled by default in the .cnf
files shipped with MySQL distributions (my-huge.cnf, my-medium.cnf,
and so forth). This affects server behavior only if you install one
of these files.
