[7.x] Add
time_series_dimension
and time_series_metric
mapping pa…
…rameters (#78265) Backports the following PRs: * Add dimension mapping parameter (#74450) Added the dimension parameter to the following field types: keyword ip Numeric field types (integer, long, byte, short) The dimension parameter is of type boolean (default: false) and is used to mark that a field is a time series dimension field. Relates to #74014 * Add constraints to dimension fields (#74939) This PR adds the following constraints to dimension fields: It must be an indexed field and must has doc values It cannot be multi-valued The number of dimension fields in the index mapping must not be more than 16. This should be configurable through an index property (index.mapping.dimension_fields.limit) keyword fields cannot be more than 1024 bytes long keyword fields must not use a normalizer Based on the code added in PR #74450 Relates to #74660 * Expand DocumentMapperTests (#76368) Adds a test for setting the maximum number of dimensions setting and tests the names and types of the metadata fields in the index. Previously we just asserted the count of metadata fields. That made it hard to read failures. * Fix broken test for dimension keywords (#75408) Test was failing because it was testing 1024 bytes long keyword and assertion was failing. Closes #75225 * Checkstyle * Add time_series_metric parameter (#76766) This PR adds the time_series_metric parameter to the following field types: Numeric field types histogram aggregate_metric_double * Rename `dimension` mapping parameter to `time_series_dimension` (#78012) This PR renames dimension mapping parameter to time_series_dimension to make it consistent with time_series_metric parameter (#76766) Relates to #74450 and #74014 * Add time series params to `unsigned_long` and `scaled_float` (#78204) Added the time_series_metric mapping parameter to the unsigned_long and scaled_float field types Added the time_series_dimension mapping parameter to the unsigned_long field type Fixes #78100 Relates to #76766, #74450 and #74014 Co-authored-by: Nik Everett <[email protected]>
