# Airflow State Store

> Persists task and asset state across retries and DAG runs using Airflow 3.3's AIP-103 key/value stores (taskstatestore, assetstatestore) and the crash-safe ResumableJobMixin. Use when the user asks about task state store, checkpointing in tasks, persisting state across retries, job IDs surviving worker crashes, watermarks, asset metadata, resumable tasks, crash-safe operators, or "what's new in Airflow 3.3". Also use proactively when reading a DAG that uses Variables or XCom for intra-task coordination state — flag the anti-pattern and recommend taskstatestore or assetstatestore instead. Also use proactively when reviewing ANY DAG that submits a job to an external system and waits for it to finish — Databricks, Snowflake, BigQuery, Redshift, Spark, dbt Cloud, EMR, AWS Batch, etc. — whether that is one submit-and-wait operator or split across a separate submit task plus a sensor/polling task; this covers waitfortermination, deferrable, durable, hand-rolled sensors polling a run/job id, and whether to collapse a submit+sensor split into one task. The taskstatestore/assetstatestore/ResumableJobMixin state-persistence pieces require Airflow 3.3+; the submit+poll architecture guidance itself applies on any Airflow version — do not skip this skill for a pre-3.3 DAG.
