Data Store

The Data Store is a key/value store that is used for temporary storage of data. It is especially useful in migrations or situations where you need to store data somewhere that gets used in a subsequent Flow.

Platform Settings

Internal

This stores data inside the Ziggy database. It is intended for scenarios where the total number of keys stores is in the hundreds of thousands. When this gets too large, the performance will slow down.

AWS

This uses AWS DynamoDB to store data. As a result, it is infinitely scalable and can contain any number of keys. When running Ziggy Solo, you will need to configure the following environment variables.

• DATA_STORE_AWS_REGION=your_aws_region
• DATA_STORE_AWS_ACCESS_KEY=your_access_key
• DATA_STORE_AWS_SECRET=your_secret

Azure

We will shortly be adding support for CosmosDB for anyone running Ziggy Solo on Azure.

Name and Key

The data store is a Key/Value store but it also provides an additional field name so you can create a namespace for your data.

The combination of name + key must be unique within the store.

Data Store Block

The Data Store Block gives you access to Data Store operations without the need to write any Javascript code.

Javascript API

You can also perform Data Store operations from the Javascript Block. The following methods are available.

Important : all methods are asynchronous.

Method	Description
fetch(fetchProps)	Retrieve keys using fetchProps whose type definition includes: • limit : maximum records to retrieve • offset : offset from start • flowUuid : flow's unique id (optional) • key : keyname (optional) • name : namespace name (optional) • data : search for data (currently exact match only, optional)
async findName(name: string, limit: number, offset: number)	Retrieve all keys within the specified namespace. • limit : maximum keys to retrieve • offset : relative to this offset value
findNameKey(name: string, key: string)	Retrieve the specified key within the specified namespace. • name : namespace • key : key
insert(name: string, key: string, data: any)	Insert a new key into the specified namespace. Will error if the namespace+key combination already exists. • name : namespace • key : key
upsert(name: string, key: string, data: any)	Insert a new key into the specified namespace if it doesn't exist, update if it does. • name : namespace • key : key
updateOneNameKey(name: string, key: string, data: any)	Update a key/value pair in the specified namespace. • name : namespace • key : key • data : data to store
deleteOneNameKey(name: string, key: string)	Delete a key/value pair in the specified namespace. • name : namespace • key : key

Data Store browser

You can browse and search for data in the Data Store using the Store Browser. This works for Internal mode only.
