 * The `AptosPricePusher` is designed for high-throughput of price updates.

 * this implementation does not use `update_price_feeds_if_necssary` and simulate the transaction
 * before submission.
 *
 * If multiple instances of this pusher are running in parallel, both of them will
 * land all of their pushed updates on-chain.
