注意: 本环境使用 elasticsearch 7.0版本开发,切勿低于此版本
有一张表,记录的数据特别的多,需要将7天前的记录,插入到Elasticsearch中,并删除原有表7天前的记录。
表结构如下:
CREATE TABLE `historic_records` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `user_id` varchar(50) NOT NULL DEFAULT '' COMMENT '用户id', `time` bigint(20) NOT NULL DEFAULT '0' COMMENT '上线/下线时间', `create_time` bigint(20) NOT NULL DEFAULT '0' COMMENT '创建时间', `update_time` bigint(20) NOT NULL DEFAULT '0' COMMENT '更新时间', `online_status` tinyint(1) NOT NULL DEFAULT '0' COMMENT '在线状态 默认1 0 离线 1 在线', `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '软删除标志:0-已删除;1-正常', PRIMARY KEY (`id`), KEY `user_id` (`user_id`), KEY `order_index` (`time`,`create_time`,`update_time`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='历史记录表';
查询sql:
select * from historic_records where create_time < unix_timestamp(date_add(cast(sysdate() as date), interval -7 day)) * 1000
删除sql:
delete from historic_records where create_time < unix_timestamp(date_add(cast(sysdate() as date), interval -7 day)) * 1000
相当于mysql中的数据库
相当于mysql中的一张表
相当于mysql中的一行(一条记录)
相当于mysql中的一列(一个字段)
一个服务器,由一个名字来标识
一个或多个节点组织在一起
将一份数据划分为多小份的能力,允许水平分割和扩展容量。多个分片可以响应请求,提高性能和吞吐量。
复制数据,一个节点出问题时,其余节点可以顶上。
可参考 https://www.elastic.co/guide/cn/elasticsearch/guide/current/inverted-index.html
设定映射,规定好各个字段及其数据类型,便于es更好地进行管理。根据mysql表结构,映射如下:
# 创建映射 _index_mappings = { "settings": { "index": { "number_of_shards": 3, "number_of_replicas": 1 } }, "mappings": { # self.index_type : { "properties": { "id": {"type": "long"}, "loid": {"type": "keyword"}, "mac": {"type": "keyword"}, "time": { "type": "date", "format": "epoch_millis" }, "create_time": { "type": "date", "format": "epoch_millis" }, "update_time": { "type": "date", "format": "epoch_millis" }, "online_status": {"type": "short"}, "status": {"type": "short"} } # } } }
解释:
索引设置,都在 settings{...} 中
number_of_shards
每个索引的主分片数,默认值是 5 。这个配置在索引创建后不能修改。
number_of_replicas
每个主分片的副本数,默认值是 1 。对于活动的索引库,这个配置可以随时修改。
映射配置,都在mappings{...} 中
属性设置,都在 properties{...} 中
Elasticsearch 支持 如下简单域类型:
字符串: string
整数 : byte
, short
, integer
, long
浮点数: float
, double
布尔型: boolean
日期: date
仔细看上面的mysql 表结构
由于 id 的类型是 bigint(20),那么在es中就是 long,表示长整形。
user_id 的类型是 varchar(50) ,在es中,有2中,分别是 text和 keyword。
这2种,是有区别的。text 会创建全文索引,支持模糊搜索。而keyword则不会,必须精确搜索才行。
由于 user_id不需要模糊搜索,因此 设置 keyword才是合理的。
create_time 虽然类型是 bigint(20),但是它存储在mysql里面,表示时间戳。
因此es中就是data,时间格式为:epoch_millis,表示微秒时间戳。
online_status 的类型是tinyint(1),在es中是 short,表示短的数字

为了方便操作 mysql,封装了一个mysql工具类,用来查询和更新数据。

## 说明 终端历史记录表,写入到elasticsearch中。 主要将(terminal.historic_record_0~63) 这64张表的7天前数据写入到elasticsearch中 并删除 64张表的7天前记录 `注意: 本环境使用 elasticsearch 7.0版本开发,切勿低于此版本` ## 配置说明 `conf.py` 是环境配置 主要修改 以下信息 ```python # mysql HOST = "192.168.0.136" USER = "root" PASSWD = "123456" DB_NAME = "terminal" PORT = 3306 # elasticsearch INDEX_NAME = "historic_record" INDEX_TYPE = "_doc" ES_IP = "192.169.3.133" ``` 请根据实际情况修改以上变量 ## 运行说明 ## 一键执行,迁移相关所有表 `python es_bulk.py` ## 查看结果 结果会输出到`output.log`文件,直接查看即可! 登录到`kibana`,查看数据是否存在 <br/> <br/> Copyright (c) 2019-present, xiao You
注意:如果是es 6.x的版本,创建索引,需要增加 index_type,否则会报错。
