Deal Ingestion
This step creates and maintains an overall list of tasks (CID, SP) to retrieval-test.The first step in the Spark protocol is to build a list of all files that should be available for “fast” retrieval. When we say “fast”, we mean that this file is stored unsealed so that it can be retrieved without needing to unseal the data first.
At least as of October 2024, each week the Spark team (Space Meridian) runs a manual deal ingestion process (Github) that scans through all recently-made storage deals in the f05 storage market actor and stores them as Eligible Deals in an off-chain Spark database, hosted by Space Meridian, the independent team that is building Spark. An Eligible Deal is the tuple (CID, Storage Provider), where the CID refers to a payload CID, as opposed to a piece CID or a deal CID. A payload CID is the root CID of some data like a file. An Eligible Deal indicates that the Storage Provider should be able to serve a fast retrieval for the payload CID.
In the future, and when Spark is compatible with Direct Data Onboarding (DDO), there will be real-time deal ingestion into the Spark Eligible Deal database when storage deals are made (GitHub tracking issue). This will mean that new SPs will not need to wait for up to a week to get a Spark score.
The end result of the Deal Ingestion step is a database of all Eligible Deals that should be retrievable.
