27. logstash-output-mongodb realizes Mysql to Mongodb data synchronization (ES and non-relational database synchronization)

This article mainly explains how to synchronize Mysql and Mongodb data through the logstash-output-mongodb plugin. The source data is stored in Mysql, and the target database is Mongodb, a non-relational database.

0. Premise

1) The source database has been installed: Mysql; 
2) The destination database has been installed: Mongodb; 
3) The logstash and related plugins logstash-output-mongodb have been installed. 
Installation steps reference: http://blog.csdn.net/laoyang360/ article/details/65448962

1. Detailed explanation of synchronization conf configuration

[root@la bin]# cat ./logstash_jdbc_mongo/jdbc_mongo.conf
input {
  stdin {
  }
  jdbc {
  ‘# 源Mysql数据库地址
  jdbc_connection_string => "jdbc:mysql://20.18.11.4:3306/tech?zeroDateTimeBehavior=convertToNull"
  #源Mysql的用户名和密码
  jdbc_user => "root"
  jdbc_password => "rot123"

  ‘ #true代表记录最后存储的关联列值
  record_last_run => "true"
  use_column_value => "true"
  tracking_column => "id"
  ‘ #存储位置
  last_run_metadata_path => "/opt/logstash/bin/logstash_jdbc_mongo/mongo_info"
  clean_run => "false"

  ‘ #jdbc路径地址
  jdbc_driver_library => "/home/lib/mysql-connector-java-5.1.38.jar"
  ‘ # the name of the driver class for mysql
  jdbc_driver_class => "com.mysql.jdbc.Driver"
  jdbc_paging_enabled => "true"
  jdbc_page_size => "500"
‘ #以下对应着要执行的sql的绝对路径。
  statement_filepath => "/opt/logstash/bin/logstash_jdbc_mongo/jdbc_mongo.sql"
‘ #定时字段 各字段含义（由左至右）分、时、天、月、年，全部为*默认含义为每分钟都更新
schedule => "* * * * *"
  }
}

filter {
json {
  source => "message"
  remove_field => ["message"]
  }
}

’#输出mongodb的配置
output {
  stdout { codec => rubydebug }
  mongodb {
‘#对应mongodb的输出集合
  collection => "N_CLASS"
’#对应mongodb的输出数据库名称
  database => "data"
  uri => "mongodb://110.0.12.45:27017"
  }
}

2. SQL that needs to synchronize the table

[root@lalogstash_jdbc_mongo]# cat jdbc_mongo.sql
select
*
from n_class
where n_class.id > :sql_last_value

3. Summary

The above realizes the full and incremental synchronization operation between a database table table in the Mysql database and a collection collection in Mongodb. 
Full realization: realized through sql statement; 
incremental realization: realized through timing and sql_last_value. 
When synchronizing, you don't need to do anything in mongodb. After synchronization, you can see the new collection collection after synchronization on the windows client of mongodb: Robomongo.

4. Off-topic (welcome to leave a message for discussion)

PS: The following link refers to the speech topic "The King of NoSQL - Migrating from Relational to MongoDB in One Minute", but so far, I have not found relevant details such as PPT and other materials. Bo friends, who has participated or a better synchronization plan welcomes comments and discussions.
