несколько входов в logstash jdbc

Я использую logstash jdbc, чтобы держать вещи syncd между mysql и elasticsearch. Его работа отлично подходит для одного стола. Но теперь я хочу сделать это для нескольких таблиц. Нужно ли открывать несколько в terminal

logstash  agent -f /Users/logstash/logstash-jdbc.conf

каждый с запросом select или у нас есть лучший способ сделать это, чтобы мы могли обновить несколько таблиц.

мой файл

input {
  jdbc {
    jdbc_driver_library => "/Users/logstash/mysql-connector-java-5.1.39-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/database_name"
    jdbc_user => "root"
    jdbc_password => "password"
    schedule => "* * * * *"
    statement => "select * from table1"
  }
}
output {
    elasticsearch {
        index => "testdb"
        document_type => "table1"
        document_id => "%{table_id}"
        hosts => "localhost:9200"
    }
}

вы можете определенно иметь одну конфигурацию с несколькими jdbc введите, а затем параметризуйте index и document_type в своем elasticsearch вывод в зависимости от того, из какой таблицы происходит событие.

input {
  jdbc {
    jdbc_driver_library => "/Users/logstash/mysql-connector-java-5.1.39-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/database_name"
    jdbc_user => "root"
    jdbc_password => "password"
    schedule => "* * * * *"
    statement => "select * from table1"
    type => "table1"
  }
  jdbc {
    jdbc_driver_library => "/Users/logstash/mysql-connector-java-5.1.39-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/database_name"
    jdbc_user => "root"
    jdbc_password => "password"
    schedule => "* * * * *"
    statement => "select * from table2"
    type => "table2"
  }
  # add more jdbc inputs to suit your needs 
}
output {
    elasticsearch {
        index => "testdb"
        document_type => "%{type}"   # <- use the type from each input
        hosts => "localhost:9200"
    }
}

это не создаст дубликатов данных. и совместимый logstash 6x.

# FIRST_TABLE :  place  
# SECOND_TABLE :  things    
# SET_DATA_INDEX : test_index_1, test_index_2
