Est-il Dieu possible, en pleine mouvance des droits de la femme, que des bougresses se plient encore aux ordres fascisants d'une espèce de Ubu prostatique de la mode, qui au lieu de crever de honte dans son anachronisme, continue de leur imposer le carcan chiffonneux de ses fantasmes étriqués, et cela, jusqu'au fin fond populaire de nos plus mornes Prisunic ? Je t'en prie, ma femme, ma soeur, mon amour, mets ton jean, ou reste nue, mais ne marche pas dans la mode, ça porte malheur. [Pierre Desproges]

Cassandra
Use cases
From https://blog.pythian.com/cassandra-use-cases/
“The ideal Cassandra application has the following characteristics:
- Writes exceed reads by a large margin.
- Data is rarely updated and when updates are made they are idempotent.
- Read Access is by a known primary key.
- Data can be partitioned via a key that allows the database to be spread evenly across multiple nodes.
- There is no need for joins or aggregates.
Some of my favorite examples of good use cases for Cassandra are:
- Transaction logging: Purchases, test scores, movies watched and movie latest location.
- Storing time series data (as long as you do your own aggregates).
- Tracking pretty much anything including order status, packages etc.
- Storing health tracker data.
- Weather service history.
- Internet of things status and event history.
- Telematics: IOT for cars and trucks.
- Email envelopes—not the contents.”
