Question

我正在使用弹性搜索，并且是这项技术的新手。我想知道“当couchdb相关文档更新时，如何自动更新elasticsearch索引行？” 例如我有像下面这样的couchdb数据购买数据库行

rows:[{
           "_id": "8ea64a80b67aff0ee12393b9",
           "_rev": "3-3d76a4f82bc4d3f8f7",
           "polines": [

                   "unit_of_measure": "BAG",
                   "unit_price": 161.00021
               }
           ]
        },

               }
           ]
        }
,{
           "_id": "8ea64a80b67aff0ee12393b995",

                   "unit_price": 181.00021
               }
           ]

        }]

这是我的数据。我为这个数据库创建了索引。然后我的要求是当我向couchdb添加一行时，它将使用nodejs在elasticsearch索引中更新。提前谢谢

Answer 1

节点进程可以监听the changes feed of CouchDB。只要它检测到更改，就让它更新elasticsearch索引。

还有CouchDB Lucene可能更容易使用，但我不确定elasticsearch是否是您项目的特定要求，并且您无法轻松更改技术堆栈。

如何在nodejs中使用elasticsearch更新couchdb时自动更新索引行
