# kvdr

Key/Value Dump and Restore (KVDR)

Simple tool to dump and restore data from Key/Value (Redis like) databases.

# Requirements

- [redis-py](https://github.com/andymccurdy/redis-py)
- [docopt](https://github.com/docopt/docopt)


# Installation

For the time being (while kvdr is under active development) I am not going to bother to upload to PyPI,
so the fastest way to install it is if you do the following:

    # Create virtual environment
    python3 -m venv $HOME/.kvdr
    # Activate it
    . $HOME/.kvdr/bin/activate
    # Install kvdr, version 0.9.8
    pip3 install git+https://gitlab.com/dejan/kvdr.git@0.9.8#egg=kvdr

In theory every useful change I made in kvdr is tagged with a new (semantic) version, so it may be that
at the time you read this there were some newer releases, so please check the GitLab page.

Installation on Windows/[ReactOS](http://reactos.org) should be as straightforward. I suggest you
try [MSYS2](https://www.msys2.org/). In MSYS2, with Python3 packages installed, the installation steps 
should be the same as above. 

# How to use

Use `kvdr` or `kvdr --help` to see the list of available options. It should look something like:

    KVDR - Key/Value Dump and Restore

    Usage:
      kvdr dump [--file=<file_name> | --screen] <redis_url>
      kvdr load (--file=<file_name>) [--dry-run] <redis_url>
      kvdr --dry-run
      kvdr (-h | --help)
      kvdr --version

    Options:
      -h --help           Show this screen.
      --version           Show version.
      --screen            Dump to the console instead of file.
      --file=<file_name>  A file where we store dumped Redis records. Default: "redis.dump"
      --dry-run           A trial run. Works only for the loading operation.

    Examples:
      kvdr dump --file=redis13.backup redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13
      kvdr load --file=redis13.backup redis://:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/3

## Data dump

    redis-cli -h localhost -a BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC -n 13 < var/test-data.redis
    kvdr dump --file=redis-dump.txt redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13

If you have just cloned the kvdr repository, but not installed anything, you can run it inside the working
directory:

    cd <path to the working directory>
    python3 -m venv $HOME/.kvdr
    # Activate it
    . $HOME/.kvdr/bin/activate
    PYTHONPATH=. python3 -m kvdr.kvdr dump --file=redis-dump.txt redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13

## Data load

Load the `redis.dump` file data into the redis://localhost/3 database

    # Let's first delete all the data in the existing database:
    redis-cli -h localhost -a BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC -n 3 | echo "flushdb\nquit"
    # Load the data    
    kvdr load --file=redis.dump redis://localhost/3

This does not work (yet):

    kvdr load --dry-run --file=redis.dump file:///blah.dat

# Credits

[Andy McCurdy](https://github.com/andymccurdy) - for writing fantastic Python library for Redis.

# Future

- Add support for memcached
- Add support for DynamoDB
- Check whether kvdr works out-of-box with [KeyDB](https://keydb.dev/)
- Design an API so users can write Dumper/Loader implementations of their own.
