Overview

The Identity mapper is the one used by default in the Throttler.

It works by informing the throttler to check exact same stores that it receives as context, without any translation.

Let’s use the following throttler, which uses Mapper::Identity implicitly.

“‘ruby throttler = Throttler.new(client: freno_client, app: :my_app) data.find_in_batches do |batch|

throttler.throttle([:mysqla, :mysqlb]) do
  update(batch)
end

end “‘

Before each call to ‘update(batch)` the throttler will call freno to check the health of `mysqla` and `mysqlb`. And sleep if any of them is not ok.
