According to ChainCatcher, Drift posted on social media that it will migrate to the Pyth oracle, and the price input will be updated from the Push oracle to the Pyth new product Pull oracle. The original Push oracle updates data every 400 milliseconds, and there is an update delay when the chain is congested.
The Pull oracle was deployed on the Solana mainnet on June 17, and can update prices on demand according to protocol requirements, ensuring that prices are updated in a timely manner during congestion.
