sending transactions from pods

[bernardoaraujor]

@pepoviola has mentioned that zombienet allows us to send the transactions from the same pod where the target node is running.

we should use this issue to discuss and brainstorm a few things:

• we'll need a script to be executed on the pod... how does this script look like, and how do we get zombienet to trigger it?
• by doing this, we are essentially eliminating the variable of network latency between transaction sender and target node... is that a desirable thing? IMO yes, but I need to reflect more

This would also relate to Versi based deployments, and indeed it is an interesting question.

IMO it is a good idea for measuring a maximum (s)TPS number which is core to the measurement, but is not very realistic. In practice, RPC clients may be located in different locations than nodes. In other words, transactions may be signed in a more distributed manner where there is some latency between validator / collator nodes and submitters of transactions.

This realistic scenario can be introduced by using the chaos mesh we have in Versi, whilst still maintaining the desired deployment strategy (i.e. on the same VM / kubernetes node as the validator/collator nodes). This way we can report metrics which are both theoretically maxima, and more realistic.
