Upgrade issues unable to upgrade the mappings for the index, field name contains dot

Elastic Stack Elasticsearch
21

I was trying to ask you. Is filter added in the mapping to improve the performance?

Because If you refer to my 1st comment wherein I mentioned error as

"unable to upgrade the mappings for the index [test_09], reason: [Field name [dv.fullId] cannot contain '.']","caused_by":{"type":"mapper_parsing_exception","reason":"Field name [dv.fullId] cannot contain '.'"}}},"status":500}

So to fix this we have removed the filter and then performed reindex to remote.

So asking you the same, removing filter will have performance impact or functionality break of application?

22

I don't see the relationship between this error message and a filter.

23

Can you tell me the impact of removing the filter?

24

Removing a filter from what?

25

Removing a filter from index mapping?

26

There is no filter in an index mapping. Or I don't recall we had that. Could you share a link to the documentation?
