Can chainD run start with X epoch?

[JeroniMan]

Hello, we used chainD and now we need relocate this service into new infrastructure. How we can start not with first epoch/block/slot, can chainD starts to sync with current state in blockchain?
I try research config and initial params into services, and finded epochStart but dont understant how it works and sets, it doesnt discribed in README and now used in

chaind/main.go

Line 149 in 4484de1

func fetchConfig() error {

.

Thanks!

Unfortunately there is no way to do this with the current chaind implementation. It's on the list to address, but not something that is coming any time soon.

The simplest way to relocate is to do a backup and restore of the database, and chaind will pick up from the point of the backup when it is started.

Thanks, we thought about this way, will try.

@mcdee hello, could you please help, is it right that for continue working chainD, enought metadata table and last epoch info in other tables (for example t_validator_balances)?
Thank you.

@mcdee Hi, we started chaind with snapshot of our old Postgres database, and it works, but t_validator_day_summaries doesnt calculate, i dont understand why, may be you know how i can run recalculating this table by another way.
Thank you!

The summarizer only runs after the chain data is synced. Is this now calculating the day summaries?
