# AzCosmosCopy

![Nuget](https://github.com/wivuu/Wivuu.AzCosmosCopy/workflows/Nuget/badge.svg)

[![wivuu.azcosmoscopy](https://img.shields.io/nuget/v/azcosmoscopy.svg?label=azcosmoscopy)](https://www.nuget.org/packages/AzCosmosCopy/)

Simple CLI application which copies azure cosmos DB database to same or different cosmos account.

![](./sample.png)

## Usage

By default the app will copy up to 10 containers in parallel with 100 documents in parallel per container. These can be tweaked with the `--pc` and `--pd` parameters to match your use-case. For example, if you you have only a few containers with tens of thousands of documents, you may want to increase the number of parallel documents and reduce the number of parallel containers. 

**Note** If your destination database account is on free tier (400 RU) the copy may fail if you do not slow down this app by changing the `parallel` arguments, as this application can quickly overwhelm your destination.

Install new

```sh

dotnet tool install -g azcosmoscopy

```

Upgrade to latest

```sh

dotnet tool update -g azcosmoscopy

```

Command line

```

Options:

  -s, --source                                   Source connection string (required)

  --sd, --source-database               Source database name (required)

  -d, --destination                         Destination connection string

  --dd, --destination-database     Destination database name

  --parallel-containers, --pc       Parallel container copies

  --parallel-documents, --pd         Parallel document copies

  -b, --bulk                                             Use bulk executor (serverless not supported)

  --dbscale                                     Destination database scale (serverless not supported)

  --dcscale                                     Destination container scale (serverless not supported)

  --version                                              Show version information

  -?, -h, --help                                         Show help and usage information

```

## Future

- Switch to Microsoft.Azure.DocumentDB from Microsoft.Azure.Cosmos for non-bulk copy pipeline

- Support passing 'strings' instead of 'objects' to pre-serialize data
