Release Notes

Added jsonIndexConfigs (map from column to config) under tableIndexConfig.
The following configs are added to json column:

• maxLevels: max levels to flatten the json object (Limit the depth of Json index #9476), int, default -1 (unlimited levels)
• excludeArray: do not flatten array, boolean, default false
• disableCrossArrayUnnest: do not unnest multiple arrays (unique combination of all elements), boolean, default false
• includePaths: only flatten the given paths, set of strings, default null (include all paths), example ["$.a.b", "$.a.c[*]"]
• excludePaths: exclude the given paths when flattening, set of strings, default null (include all paths), example ["$.a.b", "$.a.c[*]"]
• excludeFields: exclude the given fields when flattening, set of strings, default null (include all paths), example ["b", "c"]

When jsonIndexConfigs is configured, the old jsonIndexColumns will be ignored.

  ...
  "tableIndexConfig": {

    "jsonIndexConfigs": {
      "jsonColumn": {
        "excludeArray": true
      }
