Hi, back in the versions 2.x of elasticsearch i read that it was convenient creating indices per date, i think that helped our curator to delete old indices, i adopted creating indices daily, '2018.01.01' now i'm switching to ES 6.0, it only allows a single mapping per index, is still recommendable to use the index per day or just to have a single index for all data?, knowing that the stored data won't be deleted later.
I would like to know the performance implications of moving forward to a single index.
Thanks.
