canal同步mysql至elasticsearch中

由 泄露秘密 提交于 2020-02-04 06:38:23
环境准备 zookeeper集群 elasticsearch-6.8.6 canal admin-1.1.4 canal deployer-1.1.4 canal adapter-1.1.4 关于elasticsearch版本要求具体可自行百度，另需准备postman创建es索引，获取canal网址: https://github.com/alibaba/canal/ 搭建zookeeper集群 在这里直接使用docker-compose创建 version : '3.1' services : zoo1 : image : zookeeper restart : always hostname : zoo1 ports : - 2181 : 2181 environment : ZOO_MY_ID : 1 ZOO_SERVERS : server.1=0.0.0.0 : 2888 : 3888;2181 server.2=zoo2 : 2888 : 3888;2181 server.3=zoo3 : 2888 : 3888;2181 volumes : - / : /opt/compose - volumes/zk - volumes/zoo1 zoo2 : image : zookeeper restart : always hostname : zoo2 ports : -

Python property callable

由 我的未来我决定 提交于 2020-02-03 04:24:31
问题 Is there any way to have a property and a method with the same name? I mean a property that can be used the usual way and to be callable at the same time? Like this: >>> b = Book() >>> b.pages 123 >>> b.pages() 123 >>> b.pages(including_toc=False) 123 >>> b.pages(including_toc=True) 127 回答1: No, you can't. () always calls an object from the expression on its left-hand side. What this means is, that b.pages() can be read as follows: _tmp = b.pages _tmp() As you can see, methods are attributes.

elasticsearch之mappings

由 感情迁移 提交于 2020-02-02 19:28:00
前言 mappings 就相当于 关系型数据库中的 表结构 例: GET t1 { "t1" : { "aliases" : { }, # 该索引是否有别名 "mappings" : { #mappings 信息 "doc" : { #索引类型 doc "properties" : { #字段详细映射关系 在 properties中 "name" : { "type" : "text", "fields" : { "keyword" : { "type" : "keyword", "ignore_above" : 256 } } } } } }, "settings" : { #关于索引 t1 的settings 设置 "index" : { "creation_date" : "1553334893136", #索引创建时间 "number_of_shards" : "5", #主分片 "number_of_replicas" : "1", #副分片 "uuid" : "lHfujZBbRA2K7QDdsX4_wA", "version" : { "created" : "6050499" }, "provided_name" : "t1" } } } } 映射是什么? ES 中的 映射 用来 定义一个文档及其包含的字段如何存储 和索引的过程。 例如，我们可以使用映射来定义:

Update textbox based on combobox selection (.CSV/Array)

由 安稳与你 提交于 2020-02-02 16:15:42
问题 I have a .csv file containing columns. I already have a form which allows the user to insert and save the information to this .csv file. On a separate form, I created the ability to select items by their Item ID. I have a combobox which is displaying a drop down of Item IDs from the .csv file. Right now, the only Item IDs are 1000-1003. public void Items() { int itemID = 0; Inventory[] IArray = Inventory.getInv(); for (int v = 0; v < IArray.Length; v++) { if (IArray[v] != null) { itID =
