Re: DocValues or stored fields to enable atomic updates

[Emir Arnautović]

Hi Andreas,
Stored values are compressed so should take less disk. I am thinking that doc 
values might perform better when it comes to executing atomic update.

HTH,
Emir

DocValues or stored fields to enable atomic updates

[Andreas Hubold]

Hi,

I have a question on schema design: If a single-valued StrField is just 
used for filtering results by exact value (indexed=true) and its value 
isn't needed in the search result and not for sorting, faceting or 
highlighting - should I use docValues=true or stored=true to enable 
atomic updates? Or even both? I understand that either docValues or 
stored fields are needed for atomic updates but which of the two would 
perform better / consume less resources in this scenario?


Thank you.

Best regards,
Andreas
