where did this time come from? and what's the purpose of it exactly?

The external tick triggers at a regular interval of slotDuration. The inner tick was to trigger timeout, so that it doesn't take the entire slotDuration. I have updated the code to use a timer.

func (s *Service) createBatchMessageHandler(txnBatchCh chan *BatchMessage) NotificationsMessageBatchHandler {
go func() {
protocolID := s.host.protocolID + transactionsID
ticker := time.NewTicker(1 * time.Second)

it would be nice to configure this using slot duration, i think 1/3 a slot duration is reasonable, that way the node has 1/3 a slot to process the transaction messages and put them in the pool if they want. what do you think?

This is just for me to gain understanding, but what is the distinction here between a handshake and a non-handshake message when in batch processing mode, and why do they have to be handled differently?

when a notifications stream is opened (see docs on the different stream types here https://docs.rs/sc-network/0.9.0/sc_network/) the first message each side sends to each other over it is a "handshake" message, which each side validates and if they don't like it they close the stream, otherwise it stays open and the rest of the messages that are sent over the stream (by the opening side only) are the normal messages for that stream protocol, so in this case TransactionMessages

Ah okay that makes sense. I wasn't sure if handshake meant something different in this context, but this sounds like what I would think of as a typical handshake for establishing connection between peers (correct me if I'm misunderstanding though). And to clarify, the streams are one sided in this case?

Yes, After handshake the steam is unidirectional.

yeah, it's not exactly the same as a handshake for estabilishing connection/public keys, but it's a more high-level stream level handshake

is a problem in this case condition blocks the thread for more than the ticker duration? if yes, we might need to call a goroutine every tick to avoid this blocking

We are processing as many txns as possible within timeOut . If there is no data in channel then timeOut will be triggered.

But I'm asking if the process of a txnMsg takes for more than a ticker duration, for example lets say handleTransactionMessage blocks

Then we don't process it. We process it in the next block.

What's the reasoning behind the 200ms value?

Maybe name it as a constant together with a comment?

We wait 200ms if the channel is full. Not sure what should be the exact value. Any thoughts?
Named it txnBatchChTimeout

Should we have the batch size-based (event driven) on top of time-based?
In case there is a lot of messages coming in as a burst.
What do you think?

Having event-based will cause issues because in order to validate transactions we take a lock on the state trie. Block production might suffer due to this.
