- PostgreSQL: 9.3.2
- Elasticsearch: 0.90
- jprante/elasticsearch-river-jdbc: 2.2.2
- PostgreSQL JDBC: 9.3-1100 JDBC 41
我正在尝试使用elasticsearch river将postgresql的Json数据类型列导入elasticsearch。
这里是创建的river:
curl -XPUT 'localhost:9200/_river/business_river/_meta' -d '{
"type" : "jdbc",
"jdbc" : {
"driver" : "org.postgresql.Driver",
"url" : "jdbc:postgresql://localhost:5432/business",
"user" : "postgres",
"password" : "",
"sql" : "select id, active, companies->'sic'->>'national_number' AS sic, companies->'names'->>'name' AS name, companies->'address'->>'country' AS country from businesses.business",
"index" : "business",
"type" : "jdbc"
}
}'
这条河抱怨说“names”列不存在!!!在Postgresql中查询是有效的,这让我想到JDBC或这条河还不支持Json数据类型。
以下是完整的信息:
