Cosmic

A succinct and powerful command line query tool for Azure Cosmos DB.

Summary

Cosmic makes it effortless to run ad-hoc or prepared queries against your Azure Cosmos DB containers for scenarios such as:

• Selecting data
• Upserting data
• Deleting data
• Backing up data
• Troubleshooting performance or cost issues
• Sharing reusable, parameterisable queries

Cosmic is a tool for operating on existing Azure Cosmos DB collections. If you want to create and modify accounts, databases, and collections, then you should use the official Microsoft Azure CLI tool az cosmosdb.

Installation

dotnet tool install -g cosmic

Usage

Connect to an Azure Cosmos DB account:

cosmic connect -n foo -c "AccountEndpoint=https://****.documents.azure.com:443/;AccountKey=****==;"

Switch to an active container you want to work with (optional):

cosmic switch foo/db/container

Query an Azure Cosmos DB account (where 'foo' is the name of a previously created connection):

cosmic query "SELECT * FROM c"

Delete documents from an Azure Cosmos DB account:

cosmic delete "SELECT * FROM c"

You can pipe data out to a file:

cosmic query "SELECT * FROM c" > data.json

...and then upsert data back in:

cosmic upsert data.json

...or upsert a document directly:

cosmic upsert "{'id':'foo'}"

Measure RU cost:

cosmic query "SELECT * FROM c" -r

Check which container is active:

cosmic active

Store a query for later with default query parameters:

cosmic store -n myquery "SELECT * FROM c WHERE c.Type = '%%'" car

Execute a previously stored query with it's default query parameters:

cosmic query myquery

Execute a previously stored query with defined query parameter values:

cosmic query myquery boat

Output query text before result:

cosmic query myquery boat -q
