Handle ALTER TABLE without a restart #36

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently, you must restart Apache after an ALTER TABLE command, or mod_ndb 
will fail to access 
the changed table.

mysqld (in ha_ndbcluster.cc) checks for table->getObjectStatus() == 
NdbDictionary::Object::Invalid

There's the "forced graceful restart" strategy:

if (getObjectStatus() == NdbDictionary::Object::Invalid) {
   send SIGUSR1 to your own pid.
}
