How will ThreadLocal work with Virtual Threads for AbstractRoutingDataSource?

[@muralikrishnasiju]

Did you find any solution?

[@zombi1034]

@@muralikrishnasijuThreadLocal works just fine with virtual threads too. Only thing is it should not be used as a caching solution for expensive to create objects, as every virtual thread and as they are not pooled, also every task, would end up creating their own thread local instance. Maybe ScopedValue would work here? I am not sure, haven’t played around with them yet.

Could you please provide link to GitHub repo of this project

Hi, What should be the right approach for this scenario: Having an application that is tenantcy based with different database for each tenant to manage its data, let say we have more than 1k of tenants meaning 1k different databases, how efficient would be to switch between them if we determine the tenant by the request received, the typical example is to identify the tenant using a request HEADER. Thanks for your comments.

Hi Josh, thank you for sharing your knowledge. May I suggest an improvement? In the metaprogramming part, the use of the HikariDataSource instead of LazyConnectionDataSourceProxy would be more explicit in order to show the lack of call of the getConnection method. Replace: if (bean instanceof LazyConnectionDataSourceProxy db) { with: if (bean instanceof HikariDataSource db) { then you get: class com.zaxxer.hikari.HikariDataSource.getConnection() class com.zaxxer.hikari.pool.HikariProxyConnection operation: apac no operation: The no operation part exhibits no call to the getConnection() method anymore. Please note that I added the class of the invoked bean in the message.

My left ear agrees, but my right ear is not so sure.

[@ianwanjala8621]

thanks for this, I actually thought that my earphones were the issue🤣

[@nickferrara5770]

It started easy and got too advanced pretty fast

[@solysoly89]

Not useful for understanding. Too fast and no structure in how to acheiver the goal

[@olivierboisse1678]

There is no sound !!
