Last batch card in Barn is updated with a delay if place an order in Prod API

[elena-zh]

I have noticed, that Last batch card in Barn (and all the rest cards as well) are updated with a dellay if place an order in Prod, but see the stats in Barn home page.

Delay might take:

• for GC up to 6 minutes (TX 0xf058723cfa2935d5dd8a3fe7a73fa48dbd2635a87dbe124dc57602ccaadfd913)
• for Mainnet - up tp 3

As a result, the last batch ID might show irrelevant info

Expected: reduce a delay?

I have to notice, that executed orders in BARN appear immediately on cards

@elena-zh could you run some queries to the subgraphs after an order is confirmed to debug this further?

query LastBatch {
	settlements(orderBy: firstTradeTimestamp, orderDirection: desc, first: 1) {
    txHash
    firstTradeTimestamp
  }
	_meta {
		block {
			hash
			number
		}
	}
}

Mainnet subgraph: https://api.thegraph.com/subgraphs/name/cowprotocol/cow/graphql
GC subgraph: https://api.thegraph.com/subgraphs/name/cowprotocol/cow-gc/graphql

The txHash in the query should be updated accordingly.

Hey @ramirotw , I have retested the issue today.
I have to mention, that the issue is no longer relevant in GC, as the data was updated immediately there.

As for the Mainnet, the data was updated in 1 minute. I did not record the whole process, but here is the video where you can see that updated batchID appears with timing '1 minute ago':

I'm not sure if this timing is acceptable. If yes, lets close this issue.

Closing the issue as I'm no longer able to reproduce it.
