Python API

#Python API

Since ccdb command is actually written in python, there are at least 2 ways to interact with CCDB using python.

1. Using functions that very resembles 'ccdb' command

2. Using so called low level python API

Using 'ccdb' command like functions:

It looks like this:

context.process_command_line("mkdir /test/testable2 x y z #Some comment")

Procs:

• As simple as ccdb command but you get exceptions and don't have to use syscall
• Documentation from ccdb command works here too
• It is safe

Cons:

• You don't get results as python objects. So you can't read tables and do for on them

Using Low Level python API

Procs:

• Full access to CCDB data through python
• Working with python objects
• SQLAlchemy querries to DB is possible

Cons:

• More complex
• One can screw up data layout especially on delete operations (so please, follow instructions and examples, make backups!)
