solr DIH 数据配置文件的理解


 

 

 

 

  • The query gives the data needed to populate fields of the Solr document in full-import

  • The deltaImportQuery gives the data needed to populate fields when running a delta-import

  • The deltaQuery gives the primary keys of the current entity which have changes since the last index time

  • The parentDeltaQuery uses the changed rows of the current table (fetched with deltaQuery) to give the changed rows in the parent table. This is necessary because whenever a row in the child table changes, we need to re-generate the document which has that field.
