This tool is used to get the progress of all current table transitions during the online segment_2 function.

Currently, you can specify 3 dimensions (in the conf file) to view the results, you can specify one of them individually, or you can customize the combination (that is, specify multiple at the same time).

Note

We use MySQLdb python lib to fetch meta from FE, so you must install it.

You can get MySQLdb lib from https://pypi.python.org/pypi/MySQL-python, then you can install it as follows:

$ tar zxvf MySQL-python-*.tar.gz
$ cd MySQL-python-*
$ python setup.py build
$ python setup.py install

Steps

1. Fill in the conf according to your cluster configuration, and specify the table or be you want to watch.
2. Execute python show_segment_status.py

Example

1. If you want to watch the process of a table named xxxx, you can specify table_name = xxxx in conf file

2. If you want to watch the process on be whose be_id is xxxx, you can specify be_id = xxxx in conf file
