In worker#process we first export and persist all precommits/signature in the block found in LastCommit and then we export and persist the block itself. There is a foreign key in block (proposer_address) that maps to the validators table. However, the block's proposer may not exist in the validator table if the proposer is new and has never signed before.

I'm experimenting with cosmos, and I'm having some issue connecting to the RPC and LCD endpoints.

If I curl both LCD and RPC endpoints I get a reply from the network, but when I use the following config.toml to connect to the network I get the following error

{"level":"info","error":"Validators: response error: RPC error -32603 - Internal error: height must be greater than 0","height":83,"time":"2020-02-27T17:07:48Z","message":"failed to get validators for block"}

config.toml
rpc_node = "http://127.0.0.1:26657"
client_node = "http://127.0.0.1:1317"

[database]
host = "localhost"
port = 5432
name = "postgredb"
user = "admin"
password = "password"
ssl_mode = "disable"

I have setup multiple validators, and blocks are being produced normally.

Is there something wrong in my configuration?

Thanks a lot

Implement unit and integration tests to achieve at least 90% coverage.

Improve modularity and remove any assumptions about the origin chain so Juno can sync with any Tendermint-based chain.

Improve queue consumer/producer model to perhaps improve speed of syncing. Currently we have a single producer/consumer model. Although, this mostly impacts syncing from an already large existing chain.

Currently the worker naively retries every failed export:

// start starts a worker by listening for new jobs (block heights) from the
// given worker queue. Any failed job is logged and re-enqueued.
func (w worker) start() {
	for i := range w.queue {
		if err := w.process(i); err != nil {
			// re-enqueue any failed job
			// TODO: Implement exponential backoff or max retries for a block height.
			go func() {
				log.Printf("re-enqueueing failed block %d\n", i)
				w.queue <- i
			}()
		}
	}
}

A better approach is needed to not continuously retry the same heights.
