In all examples I see the database adapter set as a non-shared service. Like this:
$di->set("db", function() use ($config) {
return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
"host" => $config->host,
"username" => $config->username,
"password" => $config->password,
"dbname" => $config->name
));
});Wouldn't it be better as a shared service ?
I knew I saw it in the docs once before. It took me a second to find it:
https://docs.phalcon.io/en/latest/reference/di.html#service-name-conventions
Db and several other services default to shared.
Does it mean Phalcon\DI\FactoryDefault will set a service using the 'db' identifier as shared no matter what ?
If you are using isolated transactions you have to set the service as non-shared as it needs it to create an isolated transaction, in any other case setting the service as shared will be a safe decision.

Could you please verify your answer? I'm not sure where you meant to write "non-shared" vs "shared".

I have edited it :)
This link https://docs.phalcon.io/en/latest/reference/models.html#isolated-transactions is no longer valid as whatever isolated-transaction section that was once there is no longer referenced. I assume this is now the correct link: https://docs.phalcon.io/en/latest/reference/model-transactions.html#isolated-transactions
