but, defining the new template makes the elasticsearch indexing process slower, because using the first template ( the default one elasticsearch created automatically) indexed 500000 records in 30 minutes but the second template ( which i defined ) indexed 300000 records in 30 minutes. could you please advise me about this? how can i promote the templates to make the indexing process faster?
