Editor's Notes
- #4: Qu'est-ce que le no-sql ? Tout ce qui n'est pas SQL Le no-sql a toujours existé
- #5: Clé-valeur Orienté columns Orienté document
- #8: Pas de transaction Terminologie : Table = Collection, Ligne = Document, Index = Index Collections de collections Mongo: ACID ? ~Atomic (update)~, cohérent, isolation, durable
- #9: Pas de schéma Donnée hétérogènes (éviter M coll) Atomicité par document Terminologie : Jointure = Données embarquées
- #10: Obligatoire Clé 12 bits 4 – timestamp 3 – id machine 2 – id process 3 – compteur Non brut visible en hexa 24 caractères
- #19: Donne une idée de l'implémentation de mongo dans PHP
- #20: Pas besoin de createdAt avec l'id
- #25: Upsert : insert if unexists Multiple : all for request J : false : force sync with disk, else journal
- #29: Groupe de process mongo maintiens les mêmes données (master/slave)
- #30: Process stockage de donnée entre plusieurs machine. Si une machine ne tiens pas la charge (I/O) Haute-disponibilité avec la réplication
- #31: Qu'est-ce que le no-sql ? Tout ce qui n'est pas SQL Le no-sql a toujours existé
- #33: Compatible : Mac, windows et Linux
- #36: - ne pas l'utiliser juste pour le plaisir - pas adapté aux environnements transactionnels critiques
