# Kubernetes api server is supposed to run compaction on etcd
# when that does not happen we need to do an emergency compaction to make etcd not lock up
# this should only be done once, so we pick the leader to do it, which we assume is healthy
# (compacting manually outside of api server can lead to watches failing / requests for specific revisions failing etc)
# After compacting the keyspace, the backend database may exhibit internal fragmentation.
# Any internal fragmentation is space that is free to use by the backend but still consumes storage space.
# The process of defragmentation releases this storage space back to the file system.

Updating rails versions while keeping the business running

Updating rails versions on big apps can be dangerous and time consuming. This is the workflow we use to deploy and test our Rails upgrades in isolation, before releasing them to everybody and without blocking other changes.


ln -s Gemfile Gemfile.rails4 and use BUNDLE_GEMFILE=Gemfile.rails4 bundle exec rails c to run rails 4.

if ENV['BUNDLE_GEMFILE'].to_s.include?('rails4')
 gem "rails", "4.0.13"
