我想将下面的对象附加到流中的每个对象
{"index":{"_index":"tvseries","_type":"internindex"}}
我的流看起来像这样
[
{"showname":"The X Files","episode":"04","content":"Before what?","season":"1"},
{"showname":"The X Files","episode":"04","content":"Before what?","season":"1"},
{"showname":"The X Files","episode":"01","content":"What?","season":"1"}
]
我的流应该是什么样子!
> -> POST http://localhost:9200/_bulk {"index":{"_index":"tvseries","_type":"internindex"}}
> {"showname":"The X Files","episode":"04","content":"Before
> what?","season":"1"}
> {"index":{"_index":"tvseries","_type":"internindex"}}
> {"showname":"The X
> Files","episode":"04","content":"Great.","season":"1"}
> {"index":{"_index":"tvseries","_type":"internindex"}}
> {"showname":"The X
> Files","episode":"01","content":"What?","season":"1"}
如何在我现有的以下代码库中使用 jsonstream 来实现这一点
var stream = new ElasticsearchWritableStream(client, {
highWaterMark: 256,
flushTimeout: 500
});
pg.connect(connectionString,function(err, client, done) {
if(err) throw err;
var query = new QueryStream('SELECT * FROM srt limit 2')
var streams = client.query(query)
//release the client when the stream is finished
streams.on('end', done)
streams.pipe(JSONStream.stringify()).pipe(stream)
})
我目前正在使用的 npm 包
用于弹性搜索中的批量插入!
用于从 postgres 获取数据到流中!
缺少的部分是将 postgres 流转换为弹性可写流!关于如何实现这一目标的任何建议、指示和建议!
