I am using aliases in elastic search to interact with indexes from java application using RestHighLevelClient.
Mapping between alias and index is done on application start up. From last 10-15 days link between alias and index gets deleted suddenly and elastic search create new index with alias name on run time. This breaks my application because index created with alias name does not have proper mappings
