comparison and tests, it is found that the query performance of SOLR during index creation is very poor, because SOLR will produce Io blocking during index creation, resulting in a decline in search performance, but elasticsearch will not, because it first saves the index content to the memory, and persists the index to the hard disk when the memory is insufficient. At the same time, it also has a queue, the index is automatically written to the hard
