Need more chain event or API

[ysqi]

hi all,
I have a plan to write all block to relational database, but I am disappointed that I can't get more detailed data without changing the source code of go-ethereum.

Here's why：

1. LevelDB does not support multi-process access
2. go-ethereum only support subscribe little event (ChainEvent、ChainHeadEvent、ChainSideEvent、RemovedLogsEvent)

I want get more detail information about process new block:

• Block Data
• Transaction
• Logs
• Recipes (Used to record transaction execution results)
• State Journal （Used to track balance change details）
• Exec Tx return value ( Used to record transaction execution output) . However, this data was directly abandoned except for the deployment of new contracts.

What I want to ask is :

1. Do you support this feature? I am happy to implement them and push request if it is possible.
2. Do you have any better solutions to get the data?

thanks all.

The best way is to subscribe to chain head events, then fetching the remaining data through other API calls when there is a new block.

thanks, I think the best way is use debug_tracBlock api。
