This is how it looks like atm.

Not a fan of the letter-per-role approach. Perhaps the proposal is too compact? I can't quickly understand most of the columns.

@AhmedSoliman I tried to use the full form but to me it looks like a lot of data in one column. But maybe you are right about being too compact. Probably better to split the PARTITIONS into LEADERS, FOLLOWERS and the NODESETS to NODESETS and SEQUNCERS

This is definitely more readable; did we give up on trying to convey the sequencer-partition leader colocation status?

I would consider using singular 'LEADERorFOLLOWERheadings. The way to read the table is something like "node N is a leader for X partitions".NODESETSsounds a bit awkward but the best alternative I can offer is something longer likeNODESET-MEMBER` (in my head, that reads as "node N is a nodeset member of Y nodesets / serves Y log tail segments").

@pcholakov the sequence/partition colocation status is only denoted by the colour so far. The green on the sequencer status means it's optimal colocation, if yellow then it's not. But this might be confusing if colours are not enabled

[pcholakov]

That's perfect, I think colour is okay as this is a relatively advanced concept.
