## endpoints can have read and write properties
## Example: /query endpoint
## There are 2 routes that must do a read query against a cluster
## It expects that each HTTP request tries each route. If it fits the filter it will be enrouted
## All requests that doesn't pass through the filter tries the next route

# * IQL = Influx Query Language
