RECOVERABLE_EXCEPTIONS = When executing queries via HTTP, some errors can more or less safely be ignored and we can retry the query again. This following exception classes shall be deemed as “safe”. Taken from: github.com/lostisland/faraday/blob/master/lib/faraday/adapter/net_http.rb

[
  Errno::ECONNABORTED,
  Errno::ECONNREFUSED,
  Errno::ECONNRESET,
  Errno::EHOSTUNREACH,
  Errno::EINVAL,
  Errno::ENETUNREACH,
  Net::HTTPBadResponse,
  Net::HTTPHeaderSyntaxError,
  Net::ProtocolError,
  SocketError,
  (OpenSSL::SSL::SSLError if defined?(OpenSSL)),
].compact.freeze

NON_RECOVERABLE_EXCEPTIONS = Exception classes which hint to a larger problem on the server side, like insuffient resources. If we encouter on of the following, wo _don’t_ retry a query but escalate it upwards.

[
  EOFError,
  Zlib::Error,
].freeze

NON_RECOVERABLE_MESSAGE =

"The server has sent incomplete data" \
" (insufficient resources are a possible cause).".freeze
