David Roberts 07a0140260 [ML-DataFrame] Ensure latest index template exists before indexing docs (#46595) ... When upgrading data nodes to a newer version before master nodes there was a risk that a transform running on an upgraded data node would index a document into the new transforms internal index before its index template was created. This would cause the index to be created with entirely dynamic mappings. This change introduces a check before indexing any internal transforms document to ensure that the required index template exists and create it if it doesn't.
