Stream Orca Whirlpool swap instructions from Portal to logger. Use case: Basic data streaming with query builder. 
import { createTarget } from "@subsquid/pipes";
import { solanaPortalSource, SolanaQueryBuilder } from "@subsquid/pipes/solana";

const queryBuilder = new SolanaQueryBuilder()
  .addFields({
    block: { slot: true, hash: true },
    instruction: { programId: true, data: true, accounts: true, transactionHash: true },
  })
  .addInstruction({
    request: {
      programId: ["whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc"], // Orca Whirlpool
      d8: ["0xf8c69e91e17587c8"], // Swap instruction discriminator
    },
    range: { from: 200000000, to: 200000000 },
  });

const source = solanaPortalSource({
  portal: "https://portal.sqd.dev/datasets/solana-mainnet",
  query: queryBuilder,
});

const target = createTarget({
  write: async ({ logger, read }) => {
    for await (const { data } of read()) {
      logger.info(data, "data");
    }
  },
});

await source.pipeTo(target);
