使用 jdbc 驱动程序从 mysql 数据库更新 elasticsearch 时,我遇到了数据丢失的问题。我的河在下面:
curl -XPUT 'http://localhost:9200/_river/river_index_type/_meta' -d '
{
"type": "jdbc",
"jdbc": {
"strategy": "simple",
"driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost/tt",
"user": "user",
"password": "password",
"sql": "SELECT p.product_id AS _id, ... FROM product p ... WHERE ...",
"poll": "5m",
"autocommit": true
},
"index": {
"type": "type",
"index": "index"
}
}
最初一切正常,但后来,我的索引中的结果不是 1200,而是只有 800-900,并且每五分钟计数就会改变。我不明白问题是什么。任何帮助,将不胜感激。
