delete sweatcoin testnet accounts from load tests

[jakmeier]

Testnet state is getting large. Devs are running tests and never delete their data.

We are the worst offender here - each new sweatcoin testnet account for load test added millions of accounts, which translates to GBs of data.

Today on testnet, state sizes are:

Shard 0	Shard 1	Shard 2	Shard 3
6.8 GiB	4.7 GiB	48.3 GiB	43.6 GiB

• shard 2 is where the lockup accounts are
• shard 3 is wherethe token accounts are

we should

• figure out which accounts take up how much space
• see how easy it is to delete them (pretty sure delete account action will not work because state is too large)
• delete accounts that we have keys, communicate with Sweatcoin asking them to delete their big testnet accounts
• think about general solutions for accumulating big test state

cc @firatNEAR, nothing urgent but something I just realized we should probably do

@firatNEAR I assume the Sweatcoin tests haven't been cleaned up, yet?

cc @nikurt since you mentioned in a side comment of this epic state-parts analysis comment you want to look at why testnet contract state is so big.

My two cents: We don't know how much leftover state from Sweatcoin testing uses exactly. But we did create the full projected Sweatcoin state with 10M+ accounts on multiple near accounts. So I would expect something in the order of >10GB in terms of summed up TrieNodeWithSize::memory_usage and probably twice that in terms of disk usage.

@firatNEAR could maybe help with account names, if you actually want to dig deeper.
