Use liquibase with python. Java integration is done using Java Native Interface (JNI) using pyjnius

MySQL, Postgresql, Bigquery, Redshift JDBC Drivers included.

Installation

install from github:

pip install https://github.com/memiiso/pyliquibase/archive/master.zip --upgrade --user

How to Use

pyliquibase --defaultsFile=changelogs/liquibase.properties validate
pyliquibase --defaultsFile=changelogs/liquibase.properties updateSQL
pyliquibase --defaultsFile=changelogs/liquibase.properties update

    liquibase.status()
    liquibase.updateSQL()
    liquibase.update()
    liquibase.rollback("MyTag")

Python Java Integration

Python library is using LiquibaseCommandLine reflection class which uses/equivalent LiquibaseCommandLine java class. liquibase calls are executed by LiquibaseCommandLine.execute(liquibaseargs) method by passing given python arguments to java class.

python java integration class using pyjnius(using the Java Native Interface (JNI))

class LiquibaseCommandLine(JavaClass, metaclass=MetaJavaClass):
    __javaclass__ = 'liquibase/integration/commandline/LiquibaseCommandLine'
    # methods
    execute = JavaMethod('([Ljava/lang/String;)I')
