v4: Fetching all transactions from transaction_pool

[parazyd]

Hi, is there a way to get an index of all transactions that are currently in the transaction pool?

This functionality is necessary for one method in Electrum (and the Electrum protocol).

No, the tx pool is currently unindexed. The index has been written but not integrated yet.

So it's something you're considering implementing? At least to fetch all txids in the pool?

I suppose that might even be enough, and then fetch_transaction2 could be used while iterating over the ids.

It doesn’t search history, it collects metadata on incoming txs as they enter the pool. I’ll integrate it once the node is ready.

This is something that would be followed with the transaction subscription interface?

[evoskuil]

Unrelated, tx subscription doesn’t require an index.

Ah alright. I misunderstood then.

Thanks a lot! Looking forward to the integration :)
