Hello Hive Community Members,
With this post, let's talk about unsung hero - Union Indexer Node.
What is a union indexer node?
The union indexer is focused on indexing multiple sources of social media posts.
At the moment the indexer supports:
- Off-chain Ceramic content
- HIVE content
Those who wants to develop dApps which supports both on-chain (hive-blockchain) and off-chain (ceramic content), I recommend them reading this article. With this post, they can set-up an indexer with which off-chain & on-chain data can be easily accessible.
Why call it "Union"? Because it's a union of off-chain & on-chain data.
Do we have any union-indexer-node running?
- Yes. @spknetwork is running one union-indexer node
- https://union.us-02.infra.3speak.tv/api/v2/graphql
- DApp on which you're working, you can use that Endpoint, integrate graphQL APIs & you're all set.
Who is using such union-indexer-node at the moment?
- Yes. There are 2 DApps already running union-indexer-nodes.
- 3Speak's new Beta web-app deployed here - https://3speak-nextjs-4vvcag584-spknetwork.vercel.app/
- 3Speak's Mobile app which you can download from PlayStore & AppStore.
Did I (@sagarkothari88) run any indexer node?
- Yes. I was running a union indexer node.
- I took it down & utilising that computer for video-encoder-node.
- May be, in next post, I'll explain about how to setup a video-encoder-node.
Why to run union-indexer node?
- By having your own union-indexer-node, you can easily integrate it in your dApp
- You can access to off-chain & on-chain data with ease
- Querying with union-indexer-node is much easier.
- Data storage & system config required is much lesser compare to Hive RPC node.
