Nazev: create_email_indexes_v1.0.py
|
|
Verze: 1.0
|
|
Datum: 2026-06-08
|
|
Autor: Vladimir Buzalka (asistovano Claude)
|
|
Popis: Vytvori slozene indexy na kolekci emailu vbuzalka@its.jnj.com
|
|
v databazi `emaily` pro rychle vyhledavani:
|
|
- { recipients.email: 1, received_at: -1 } -> prijemce + datum
|
|
- { sender.email: 1, received_at: -1 } -> odesilatel + datum
|
|
Indexy jsou v pozadi (background) a idempotentni (create_index
|
|
nic neudela, kdyz uz existuji se stejnym klicem/nazvem).
|
|
Pozn.: Pred spustenim ukazat nahled; vytvoreni indexu je nedestruktivni.
