Archives are an important piece of Polkadot and Kusama data infrastructure provided by Subsquid. They provide access to on-chain data in GraphQL format for all major parachains on Kusama and Polkadot, with more chains getting support as the ecosystem grows. They are being used as a data source for Squids and for efficient data exploration and ad-hoc queries. An up-to-date list of Archives is kept in a public Archive Registry
Over the course of Q4, Subsquid released incremental upgrades to the SDK, including:
The data collection pipeline has undergone some changes, and because of this, there are some gaps in the available data (which also influence the weekly moving average in red).
With that being said, it is reasonable to assume a linear trend, and the red line represents a linear regression estimation of total queries over time. The gaps in the collected data are visible as "flattened" sections of the blue line in the chart:
Under this assumption, we can extrapolate these key metrics about Subsquid's Archive infrastructure, over the course of Q4 2023:
