Dynamic dispatch forces heap allocation and adds extra overhead.
Dynamic casting as in the ones below, lacks compile-time type safety:
https://github.com/solana-labs/solana/blob/eeb622c4e/quic-client/src/lib.rs#L172-L175https://github.com/solana-labs/solana/blob/eeb622c4e/udp-client/src/lib.rs#L52-L55
The commit removes all instances of Any, Box<dyn ...>, and Arc<dyn ...>,
and instead uses generic and associated types.
There are only two protocols QUIC and UDP; and the code which has to
work with both protocols can use a trivial thin enum wrapper.
With respect to connection-cache specifically:
* connection-cache/ConnectionCache is a single protocol cache which
allows to use either QUIC or UDP without any build dependency on the
other protocol.
* client/ConnectionCache is an enum wrapper around both protocols and
can be used in the code which has to work with both QUIC and UDP.

tpu-client/tpu_connection_cache is refactored out the module and moved to connection-cache/connection_cache and the logic in client/connection_cache is consolidated to connection-cache/connection_cache as well. client/connection_cache only has a thin wrapper which forward calls to connection-cache/connection_cache and deal with constructions of quic/udp connection cache for clients using them both.2.
The TpuConnection is refactored to ClientConnection to make it generic and functions renamed to be proper for other workflows. eg. tpu_addr -> server_addr, send_transaction --> send_data and etc...
The enum dispatch is removed so that we can make the bulk of code of quic and udp agnostic of each other. The client is possible to load quic or udp only into its runtime.
The generic type parameter in the tpu-client/tpu_connection_cache is removed in order to create both quic and udp connection cache and use the object to send transactions with multiple branching when sending data. The generic type parameters and associated types are dropped in other types in order to make the trait "object safe" for this purpose.
I have annotated the code explaining the reasoning and the refactoring source -> destination.
There is no functional changes
bench-tps has been performed for rpc-client, thin-client and tpu-client. And it is found the performance number largely match the ones before the refactoring.

Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case

separated durable nonce and blockhash domains, which will stop double
execution going forward. However it is possible that a durable
transaction has *already* been executed once as a normal transaction and
it is now a valid durable transaction. #25744 cannot stop such
transactions to be re-executed until the nonce accounts are advanced.
This commit adds a new nonce version indicating that the nonce is moved
out of the blockhash domain, and permanently disables durable
transactions for legacy nonces which are in the blockhash domain.
* client: Remove static connection cache, plumb it instead
* Add TpuClient::new_with_connection_cache to not break downstream
* Refactor get_connection and RwLock into ConnectionCache
* Fix merge conflicts from new async TpuClient
* Remove `ConnectionCache::set_use_quic`
* Move DEFAULT_TPU_USE_QUIC to client, use ConnectionCache::default()
AdvanceNonceAccount instruction updates nonce to blockhash. This makes it
possible that a durable transaction is executed twice both as a normal
transaction and a nonce transaction if it uses blockhash (as opposed to nonce)
for its recent_blockhash field.
The commit prevents this double execution by separating nonce and blockhash
domains; when advancing nonce account, blockhash is hashed with a fixed string.
As a result a blockhash cannot be a valid nonce value; and if transaction was
once executed as a normal transaction it cannot be re-executed as a durable
transaction again and vice-versa.
In PR review https://github.com/solana-labs/solana/pull/24083/files#r852661162. We are concerned the leader info might be out dated if the retry queue is long causing large number transactions sent to outdated leaders and increasing the load in the network.
A leader info refresher is used to ensure the leader info is up-to-date before being used in sending transactions. The refresher can update the new leader with updated endpoints.
Introduced flag --tpu-do-batch2.
Introduced flag to control the batch size-- by default 100
The default batch timeout is 200ms -- configurable. If either it time out or the batch size is filled, a new batch is sent
The batch honor the retry rate on the transaction already sent before.
Introduced two threads in STS: one for receiving new transactions and doing batch send and one for retrying old transactions and doing batch.6.
