# Basic Kudu-Python examples
This directory contains basic examples of usage for the Kudu Python client.
These examples demonstrate the standard capabilities within the client:

- **basic_example.py**: Basic CRUD operations (create, read, update, delete)
- **non_unique_primary_key.py**: Working with non-unique primary keys and auto-incrementing columns
- **array_example.py**: Using array data types with insert, scan, update, and delete operations

## To install the Python client

### Building from source
It's assumed the commands below are run from the directory where
this README.md file is located, i.e. from
`$KUDU_HOME/examples/python/basic-python-example`.

_NOTE:_ This example assumes that all Kudu C++ components are already
built in `$KUDU_HOME/build/latest`. That directory is pointing to the
latest build, which is often times a debug build. If this is not the
desired approach, you will need to point the `latest` symbolic link
to the release build Kudu directory.

```
export KUDU_HOME=/path/to/kudu
export LD_LIBRARY_PATH=$KUDU_HOME/build/latest/lib/exported
# For OS X
export DYLD_LIBRARY_PATH=$KUDU_HOME/build/latest/lib/exported
pushd $KUDU_HOME/python
pip install -r requirements.txt
python setup.py build_ext --inplace
python setup.py install
popd
```

### Installing from pypi
_NOTE:_ This example is pointing to the latest build, which is often
times a debug build. If this is not the desired approach, you will
need to point this to the release build.
```
export KUDU_HOME=/path/to/kudu
export LD_LIBRARY_PATH=$KUDU_HOME/build/latest/lib/exported
# For OS X
export DYLD_LIBRARY_PATH=$KUDU_HOME/build/latest/lib/exported
pip install kudu-python
```

## Running the examples
```
# Run the basic example
python basic_example.py --masters master1.address --ports 7051

# Run the non-unique primary key example
python non_unique_primary_key.py --masters master1.address --ports 7051

# Run the array data type example
python array_example.py --masters master1.address --ports 7051
```
