Unable to override default options

[Sean van Mulligen]

We recently encountered an issue where we were unable to override the default options for a specific query. We set defaults for distribute_reads like this:

DistributeReads.default_options = {
  max_lag: 1,
  lag_failover: true,
  failover: true
}

We have a specific query that we want to prevent from falling back to the primary db:

distribute_reads(max_lag: 100, lag_failover: false) do
    # Expect this to raise DistributeReads::TooMuchLag if replication lag is > 100 seconds
    my_query
end

However, we are still seeing this query running on the primary db when there is significant replication lag. Is there some other setting we are missing, or is it not possible to override the lag_failover default?

We are on version 0.3.5 of distribute_reads.

Hi @seanvm, I'm not sure how to reproduce. You'll also want to pass failover: false if you never want it to run on primary.
