A sample pipeline/DAG for Airflow
  1. Fetch some json/XML file from an external API
  2. Store the file on S3 (as a backup) with a file name with a i.e. a timestamp. Pass the filename on to next task
  3. Read the json/xml from S3 and into some table structure (pandas, agate etc) and change field types etc.
  4. Store the table in a postgres database in a temp table
  5. Compare the temp table to a "main" table and see if there are changes (some SQL diff). Find out which records have to be added/removed/updated in the "main" table.
  6. If nothing has changed, abort everything. If it has, pass on which records are new, deleted and updated.
  7. a) insert new records in main table, alert newsroom on slack of new items.b) delete items in main table not in temp-table. Alert via slack. c) Update records in main table, alert via slack
  8. The end

Agate compute method to generate streaks of consecutive values in a dataset. WIP
import agate
class Streaks(agate.Computation):
Computes the streaks of consecutive values in a column.
Each streak will be given an increasing
integer value so that you can group by this later to
find longest consecutive streak.
