The Sync process streams all chain data from the appropriate chain, processes this data into IPLD objects
|
|
and publishes them to IPFS. It then indexes the CIDs against useful data fields/metadata in Postgres.
|
|
|
|
The Serve process creates and exposes a rpc subscription server over ws and ipc. Transformers can subscribe to
|
|
these endpoints to stream
|
|
|
|
The BackFill process spins up a background process which periodically probes the Postgres database to identify
|
|
and fill in gaps in the data
