|
//! Generic Transaction Pool
|
||||||
|
//!
|
||||||
|
//! An extensible and performant implementation of Ethereum Transaction Pool.
|
||||||
|
//! The pool stores ordered, verified transactions according to some pluggable
|
||||||
|
//! `Scoring` implementation.
|
||||||
|
//! The pool also allows you to construct a set of `pending` transactions according
|
||||||
|
//! to some notion of `Readiness` (pluggable).
|
||||||
|
//!
|
||||||
|
//! The pool is generic over transactions and should make no assumptions about them.
|
||||||
|
//! The only thing we can rely on is the `Scoring` that defines:
|
||||||
|
//! - the ordering of transactions from a single sender
|
||||||
|
//! - the priority of the transaction compared to other transactions from different senders
|
||||||
|
//!
|
||||||
|
//! NOTE: the transactions from a single sender are not ordered by priority,
|
||||||
|
//! but still when constructing pending set we always need to maintain the ordering
|
||||||
|
//! (i.e. `txs[1]` always needs to be included after `txs[0]` even if it has higher priority)
|
||||||
|
//!
|
||||||
|
//! ### Design Details
|
||||||
|
//!
|
||||||
|
//! Performance assumptions:
|
||||||
|
//! - Possibility to handle tens of thousands of transactions
|
||||||
|
//! - Fast insertions and replacements `O(per-sender + log(senders))`
|
||||||
|
//! - Reasonably fast removal of stalled transactions `O(per-sender)`
|
||||||
|
//! - Reasonably fast construction of pending set `O(txs * (log(senders) + log(per-sender))`
|
||||||
|
//!
|
||||||
|
//! The removal performance could be improved by trading some memory. Currently `SmallVec` is used
|
||||||
|
//! to store senders transactions, instead we could use `VecDeque` and efficiently `pop_front`
|
||||||
|
//! the best transactions.
|
||||||
|
//!
|
||||||
|
//! The pending set construction and insertion complexity could be reduced by introducing
|
||||||
|
//! a notion of `nonce` - an absolute, numeric ordering of transactions.
|
||||||
|
//! We don't do that because of possible implications of EIP208 where nonce might not be
|
||||||
|
//! explicitly available.
|
||||||
|
//!
|
||||||
|
//! 1. The pool groups transactions from particular sender together
|
||||||
|
//! and stores them ordered by `Scoring` within that group
|
||||||
|
//! i.e. `HashMap<Sender, Vec<Transaction>>`.
|
||||||
|
//! 2. Additionaly we maintain the best and the worst transaction from each sender
|
||||||
|
//! (by `Scoring` not `priority`) ordered by `priority`.
|
||||||
|
//! It means that we can easily identify the best transaction inside the entire pool
|
||||||
|
//! and the worst transaction.
|
||||||
|
//! 3. Whenever new transaction is inserted to the queue:
|
||||||
|
//! - first check all the limits (overall, memory, per-sender)
|
||||||
|
//! - retrieve all transactions from a sender
|
||||||
|
//! - binary search for position to insert the transaction
|
||||||
|
//! - decide if we are replacing existing transaction (3 outcomes: drop, replace, insert)
|
||||||
|
//! - update best and worst transaction from that sender if affected
|
||||||
|
//! 4. Pending List construction:
|
||||||
|
//! - Take the best transaction (by priority) from all senders to the List
|
||||||
|
//! - Replace the transaction with next transaction (by ordering) from that sender (if any)
|
||||||
|
//! - Repeat
