Hey guys, My index holds 10.000s of fields with unknown name and type. I only know the name and type when the data "arrives" and it has to be indexed immediatly. Unfortunately, I cannot use autodetection. So, my idea was to put the mapping on EVERY single call OR do a "mapping exists?" request before. Do u know what is cheaper ? ("always put mapping" vs. "only put, if mapping doesn't exist"). Thx ! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
