liquisource 1.2.1

A liquibase datasource client for python

liquibase数据源驱动

liquibase引入python3脚本，统一管理管理mongo、clickhouse的库表结构。changelog记录还是选在记录到mysql中，这样业务上会更加灵活

<changeSet id="xxxxx" author="xxxxxx" labels="mongo">
    <comment>xxxxx</comment>
    <executeCommand executable="python3">
        <arg value="script/db_tag/creat_collection.py"/>
    </executeCommand>
</changeSet>

#!/usr/bin/env python3

def create_tag_database():
    # 获取mongo链接实例
    client = get_client(filepath)


    return client[db]


def create_tag_collection():
    # 获取mongo链接实例
    db_name = get_tenant_shard(tag_database)
    client = get_client()
    db = client[db_name]

    # db开启分片
    client.admin.command("enableSharding", db_name)

    db.create_collection(tag_collection)

    # 创建索引
    coll = db[tag_collection]
    coll.create_index(
        [("id", 1), ("name", 1)])
