What performance impact are you fearing, specifically? I mean, the Configuration hosts the reflection cache for those into(Class<?>) calls, which would then be repeated per tenant. But other than that, what specific measurements have you taken to think that a Configuration is costly (per tenant)? How many tenants do you have?
A future version of jOOQ will look into improving the PolicyProvider SPI to be context aware, see: https://github.com/jOOQ/jOOQ/issues/16311 https://groups.google.com/g/jooq-user/c/TT9PbfQlG8w/m/o5VE8vyGAQAJ?pli=1 In the meantime, you could pass tenant IDs to your policy provider using ThreadLocals, for example, or some other way to set variables like a tenant into some "scope". I hope this helps, Lukas On Thu, Jun 6, 2024 at 8:44 PM 'Bernd Huber' via jOOQ User Group < jooq-user@googlegroups.com> wrote: > Hello all, > > i would like to use the Policies Feature in Jooq-Express, > and tested it in the Trial-Version. > > It is working fine, > but i found some small things i want to ask about. > > I have a "ConfigurationFactory" (in my quarkus-app) that should create the > Jooq-Configuration only once (for performance-reasons). > > I used to do it like this: > > public class Database1ConfigurationFactory { > private Configuration configuration; > public Configuration getConfiguration() { > if (configuration == null) { > ... > configuration = new DefaultConfiguration() > ... > } > } > } > > But now, when i also add the Policies for the Tenant Check, i need to pass > the tenantId to the getConfiguration() function, so now the function > suddendly needs to return unique Configuration instances, for each tenantId. > > I fear that this will negatively affect my performance. > > It would look like this: > > public class Database1ConfigurationFactory { > private Configuration configuration; > public Configuration getConfiguration(Integer tenantId) { > ... > configuration = new DefaultConfiguration() > configuration.set(new DefaultPolicyProvider() > .append(CUSTOMER, CUSTOMER.CUSTOMER_ID.eq(tenantId)) > ... > ); > ... > return configuration > } > } > > am i implementing this correctly (as intended) or is there another way to > apply the policies afterwards (maybe in a listened, like the > executionlistener or something similar?) > > greetings, Bernd > > -- > You received this message because you are subscribed to the Google Groups > "jOOQ User Group" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to jooq-user+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/jooq-user/9dfec149-8533-4280-bf09-86a2a38b72e2n%40googlegroups.com > <https://groups.google.com/d/msgid/jooq-user/9dfec149-8533-4280-bf09-86a2a38b72e2n%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "jOOQ User Group" group.
