As soon as, I would love to have MVP.
However, some things are slowing me down.
1. Architecture choice
a. Time Warp
The ideal solution we have described with @Maar-io is that we have marketplace contract that should emit Register(collection: Account32, medatada: BoundedVec<u8>)
When this event is registered by the SubSquid indexer it should spawn a new SubIndexer that would fetch this (PSP34) contract.
However, as I mentioned in #3. The only indexer I have seen is from Talisman, and the architecture suffers a lot.
b. Factory
The second possible solution is to abandon any smart contracts outside the Marketplace Factory contract.
However, this has a few issues:
There is currently no filtering for events (Something that EVM has)
Since BatchProcessor has terrible DX (sorry to be harsh), It spawns many unnecessary logs that need to be manually processed.
Quick :adhesive_bandage: : skip using the batch processor. (Faster to implement/ slower for indexing)
Still missing filter, as said in #4
c. Dima's dirty hacking
As I already spoke with @dzhelezov (15 Dec 2022 at 17:27:28), he suggested:
I'd rather do the following.
1) make a separate job/squid that outputs a list of contracts to track
2) once a day start a new squid which indexes this contracts from scratch
3) once done, switch the endpoint
That means
I suggest a cron job that does sqd deploy , sqd prod and sqd kill
so once a day: a json with contracts is generated. A new squid is deployed, it indexes only the contracts in the JSON (it is read on init)
when it's in sync, the old squid is killed, and the alias is switched to the new one
This solution can break in three parts:
Since we need two indexers, something can be out of sync.
Maybe If there are too many contracts, can it happen that the indexer won't be able to sync?
