🔧 How Durable Checkpointing Works

1️⃣
Task Runs
Long-running analysis processes data in chunks
2️⃣
Checkpoint Created
Every 10s, state is serialized and compressed
3️⃣
Two-Phase Commit
Blob → GCS, then metadata → BigQuery
4️⃣
Recovery Ready
If crash occurs, resume from last checkpoint

📊 Verify in BigQuery

SELECT session_id, checkpoint_seq, created_at, trigger, size_bytes
FROM `test-project-0728-467323.adk_metadata.checkpoints`
ORDER BY created_at DESC LIMIT 10;
