### _#general_

  
 **@nguyenhoanglam1990:** hi team  
 **@nguyenhoanglam1990:** is it possible to create a table name and schema
name according to the system date  
**@npawar:** there isn’t a way to do that automatically in Pinot. You’d have
to write some scripts to generate those names and set in the json  
**@npawar:** what’s the usecase? why do you need this feature?  
 **@noahprince8:** What do people generally use for dashboarding with Pinot? I
see there’s no Grafana plugin  
**@tanmay.movva:** If it is a BI kinda use case. I think presto-pinot plugin
would work with many tools. Here is a blog post around pinot with superset.  
**@joe.quinn:** Hey guys, we are Facet, we are working on a slice/dice front
end for Pinot. It's in beta with a few customers now. Intention is to offer it
more to business users vs. developers. Let me know if this would be of
interest?

###  _#troubleshooting_

  
 **@contact:** @contact has joined the channel  
 **@noahprince8:** How does Helix handle a server that has all of one table’s
segments on it with replica count 1? It seems like it isn’t sending that out
to another server when it starts up. It’s just keeping the old dead server in
the ideal state. Is there something manual that has to be done?  
 **@g.kishore:** is the dead server still part of the cluster?  
 **@noahprince8:** Yeah it’s still listed in the cluster manager. But I can’t
drop it because it’s part of the ideal state  
 **@noahprince8:** But I thought it would get removed from the ideal state
when it’s dead? And another server has no segments so can replace it?  
**@tanmay.movva:** You can remove the dead instance and trigger the rebalance
endpoint. iinw.  
**@g.kishore:** thats in auto helix mode - in custom helix mode, you need to
untag that node, rebalance and then drop the dead node  
**@g.kishore:**  
**@noahprince8:** Can I enable auto helix mode, or not with Pinot?  
**@g.kishore:** we don't recommend it  
**@g.kishore:** you dont need it if you start using logical instance id's  
**@g.kishore:** you are probably facing this bcos your ips are changing  
**@g.kishore:** you can avoid this by passing a stable instanceName  
**@noahprince8:** Yeah. Rebalance seemed to work

###  _#segment-cold-storage_

  
 **@noahprince8:** The PR for this feature Dunno if it’s just the permissions,
or github’s user interface has changed for the worst since I last used it
--but I can’t figure out how to add reviewers or labels.  
 **@g.kishore:** I think only committers can do that
