I'm trying to limit number of records aggregated by Data table visualization to 500 first results.
I've updated kibanaSavedObjectMeta.searchSourceJSON of my saved visualization object as follows:
{
  "index": "logstash-*",
  "size": 500,
  "query": {
    "query_string": {
      "query": "*",
      "analyze_wildcard": true
    }
  },
  "filter": []
}
i.e. added "size": 500 parameter, but it doesn't work at all. Is there any way to do it? I need to apply limit before_aggregation, not after like SQL limit keyword does.
