How to encrypt and decrypt with AES in pycryptodome (Crypto.Cipher.AES): GCM first, CBC when required

Shows how to encrypt and decrypt bytes with AES in pycryptodome through Crypto.Cipher.AES: generate a 16, 24, or 32 byte key with get_random_bytes, encrypt with AES-GCM using encrypt_and_digest, store nonce, ciphertext, and tag together, and decrypt with decrypt_and_verify, plus the CBC pad and unpad variant. Use when…

elementary data quality test failed error "table anomalies: row count anomaly detected"

Do not widen the anomaly bounds to silence it: open the Elementary test result, read the observed row count against the training window average and standard deviation, and check whether a real load change explains the jump before touching the test configuration. Use when an Elementary-monitored dbt project where a tab…

how to fix schema drift failure: column renamed upstream breaks dbt model error

A renamed upstream column breaks every model that selects the old name: find the new name by diffing the source schema, update the source definition and the affected models, and add a compatibility alias during the transition if other consumers still use the old name. Use when dbt models breaking after an upstream col…
