What does Datafast Runtime do?

❤️ Performance-focus - it is built to prioritize indexing speed

❤️ Blockchain data reusability - block data is stored in Object Storage for reusability, eliminating cost of calling JSON-RPC over and over again for the same data

❤️ Blockchain data is smartly organized & compressed using Databricks' DeltaLake technology plus Protobuf on top for storage-efficiency, very fast serialization, very fast to ingest and unlimited scalability

❤️ Indexed data is stored in NoSQL database to reduce database cost yet still fast in retrieval

❤️ Allowing user to specify a limit time to keep output data in store, like last 6 months or last year - help reduce data storage cost by remove outdated data

❤️ Graceful reorg-handling

❤️ Extensible - as Datafast code base is way simpler and extensible than graph-node, allowing user to freely implement more features without crying for help

❤️ No need IPFS!

❤️ No GAS required for indexing!

What Datafast Runtime cannot do...

❌ Datafast Runtime is built to focus on the indexing-job. It does not come with a GraphQL query layer.

🚧 Development Status

Datafast is built for educational & sharing purpose & not ready for production - since there are plenty of features that needs implementing & issues need addressing.

Still, Datafast-Runtime can be used as a ground-work to build in-house blockchain indexing solution to replace GraphNode / TheGraph

🔰 Who is this runtime for?

• Companies who want to host their own subgraph data

• Companies who want to host their own subgraph data with efficient storage cost, with their own solution

• Developers who want to play around with their own version of Subgraph Indexing Engine

• Developers who want to play around with WebAssembly technology and build crazier stuffs with it.
