  1. When querying raw.transactions, if you do not need failed/voting txns, you can use raw.success_nonvoting_transactions

    a. if so, for (inner)instructions, use filters of parent_tx_success=true and is_voting=false

    b. for tx meta columns, the rpc returns pre/post token/native balances. we have reformatted these cols to be more user-friendly in the columns sol_amounts, mint_to_decimals, token_accounts for your convenience. (only available for success_nonvoting_transactions). For more info, refer to transaction-level columns.
