Официальная документация гласит: «Каждый запрос должен иметь отдельный jdbc»: Настройка нескольких операторов SQL
Вот сценарий:
getTableNames.py
import MySQLdb
# custom made class, Generate
from package_name.generate_conf_yml_logstash import Generate
connection = MySQLdb.connect(host="localhost:3306",
user="root/sa", password="password", db="database_name")
cursor = connection.cursor()
cursor.execute("show tables")
tables = cursor.fetchall()
application_name_tables = []
for table in tables:
application_name_tables.append(table[0])
cursor.close()
connection.close()
Generate.save_files(application_name_tables)
generate_conf_yml_logstash.py
import sys
import os.path
class Generate:
@staticmethod
def save_files(tables):
# save config files
save_path = "D:\folder_name"
for table in tables:
init_f = save_path + "\initial_logstash.conf"
conf_f_name = table + ".conf"
save_file = os.path.join(save_path, conf_f_name)
with open(init_f, "r") as original: # read only
data = original.read()
data = data.replace("table_name", table)
with open(save_file, "w+") as conf: # overwrite if exist
conf.write(data)
# save yml file
yml_f_name = "init_logstash_pipelines.yml"
save_file = os.path.join(save_path, yml_f_name)
with open(save_file, "r") as original:
data = original.read()
with open(save_file, "a+") as yml: # append
for table in tables:
data = data.replace("table", table)
yml.write(data)
sys.exit()
И примеры файлов конфигурации и YML:
init_logstash_pipelines.yml
- pipeline.id: table
path.config: "../config/table.conf"
pipeline.workers: 1
initial_logstash.conf
input {
jdbc {
jdbc_driver_library => "../logstash-6.3.0/logstash-core/lib/jars/mysql-connector-java-5.1.46-bin.jar"
jdbc_driver_class => "com.mysql.jdbc.Driver"
jdbc_connection_string => "jdbc:mysql://Mysql:3306/database_name"
jdbc_user => "root"
jdbc_password => "password"
statement => "SELECT * from table_name"
# schedule => "* * * * *"
}
}
output {
stdout { codec => json_lines }
elasticsearch {
hosts => ["localhost:9200"]
index => "table_name"
# as every table has diff. primary key, change this please
document_id => "%{pk}"
}
}
Пожалуйста, не стесняйтесь изменять исходные файлы conf, yml и код в соотв. на ваши нужды
