ResilientDB kv-Service Python API(Get and Set Command)

Description

This API allows users to use kv-service of the ResilientDB in Python directly.

How to Run

1. Make sure to run ./INSTALL.sh in advance.
2. cd to incubator-resilientdb/api folder.
3. Run command bazel build :pybind_kv_so.
4. From kv_operation.py, import get_value and set_value functions into your Python file to use it (Make sure to use the same Python version when running bazel build command and calling the functions).

Parameters

set_value:

1. key: The key user wants to store in a key-value pair. Acceptable types are str, int, float.
2. value: The corresponding value to key in the key-value pair. Acceptable types are str, int, float.
3. config_path (optional): The path to the user's blockchain config file (IP addresses). If the user does not specify this parameter, the system will default to the address located in “ip.address.config.” The acceptable type is str.

get_value:

1. key: The key user wants to get in a key-value pair. Acceptable types are str, int, float.
2. return: \n if the corresponding value of key is empty, otherwise is the corresponding value of key.

Example

import sys
# Your path to ResilientDB api folder
sys.path.append("/home/ubuntu/Desktop/incubator-resilientdb/api")
from kv_operation import set_value, get_value

set_value("test", "111222")
get_value("test")

If having set up the environment parameter, “sys.path” can be ignorred.

export PYTHON_PATH="/home/ubuntu/Desktop/incubator-resilientdb/api":PYTHON_PATH

from kv_operation import set_value, get_value

set_value("test", "111222")
get_value("test")
