ActiveRecord table_name线程安全吗？

Question

I have a multi-threaded Rails application (using Sidekiq), and in each of the threads I am setting table_name for SomeModel to a different table name

Example:

Thread 1:
SomeModel.table_name = "temp_table1"

Thread 2:
SomeModel.table_name = "temp_table2"

Is this thread-safe?

In other words, if I set it to "temp_table1" in thread 1, is there anyway for thread 2 or another thread to see this change, or is it only applicable for thread 1?

I'm using vanilla Ruby.

Answer 1

Setting a variable in MRI is thread safe. Once you update the value at thread 1, all other threads will see this same value.
