Observed behavior
As the number of attributes for a product increases, the indexing cost increases, sometimes dramatically. This can lead to the indexing operation hanging.
Expected behavior
As the number of product attributes increases, the indexing process time increase should be at worst, linear.
Resolution
Product attribution is implemented as dynamic index fields in the Product index, using the attribute identifier as part of the index field name. As the number of attributes increases, an Elasticsearch indexing phenomenon known as "map explosion" can occur. The indexing structure was altered to use a static index field mapping instead and thereby avoid indexing with dynamic field names.
