GdbDataRemover depends on:

• gremlinpython
• argparse
• futures

The following command can be used to install all of them:

pip install -r requirements.txt --user

As GDB supports transaction, all operation in a DSL execute in the same transaction. If simpely run g.V().drop() towards an instance with lots of data, the query will fail caused by limitation of transaction buffer.

GdbDataRemover supports four scenarios:

• Drop all vertices inside GDB (Including related edges)
• Drop vertices with specified Label inside GDB (Including related edges)
• Drop all edges inside GDB
• drop edges with specified Label inside GDB

The tool wil drop data with limitation (default 500) speficied by user.

Hints for parameters below：

• gdb_end_point： format looks like 'gds-xxx.graphdb.rds.aliyuncs.com'
• gdb_port：When use internal address，port is 8182；When use public address，port is 3734
• edge: When timeout Exception during drop vertices, please try to drop edges at first by add --edge

A tool for GDB Loader which imports OSS data to GDB, it could make requests as follow:

• Add new task to import CSV file(s) on OSS to GDB
• Get the task list on GDB, return the task loaderId(uuid) list
• Get detail info of one task, include process records, errors
• Delete a task, it will stop the running task at first

This tool is just a simple shell of GDB OSS Loader, you could integrate it to your project as an example

python GdbLoader.py --host ${gdb_end_point} --port ${gdb_port} --username ${gdb_user} --password ${gdb_pwd} --todo add_task --source ${source} --arn ${ramRoleArn}

# or

python GdbLoader.py --host ${gdb_end_point} --port ${gdb_port} --username ${gdb_user} --password ${gdb_pwd} --todo add_task --source ${source} --ak ${accessKey} --sk ${secretKey}

python GdbLoader.py --host ${gdb_end_point} --port ${gdb_port} --username ${gdb_user} --password ${gdb_pwd} --todo get_task --loaderId ${uuid}

python GdbLoader.py --host ${gdb_end_point} --port ${gdb_port} --username ${gdb_user} --password ${gdb_pwd} --todo delete_task --loaderId ${uuid}

python GdbLoader.py --host ${gdb_end_point} --port ${gdb_port} --username ${gdb_user} --password ${gdb_pwd} --todo list_task
