S2 (Simple Storage component)

Description

Purpose

Main goal of this component is to provide simple possibility to store and retrieve Key:Value pairs.

How works

Under the hood used MongoDB. During Action configuration collection need to be specified.

Requirements

Instance of MongoDB with possibility to connect from component.

Environment variables

No.

Credentials

hostname - Hostname or IP address of MongoDB server.

port - Port which is used by your MongoDB server to accept connection. (Default is 27017)

db - Database name that is used to store collections with Key:Values

user - MongoDB username with access to read and write from/to corresponding DB and collection.

pass - Password for specified user.

Actions

Store

Inserts Key:Value pair.

Input fields:

keyName - Name of a field where key will be stored

key - Value of a key that uniquely identifies Key:Value pair

valueName - Name of a field where value will be stored

value - Value that will be stored and can be accessed with provided keyName and key

If checkbox "Update if exists?" checked then value would be updated if already exists.

Resulting document stored in MongoDb will have following structure:

{
    keyName: key,
    valueName: value
}

If another valueName will be stored with the same keyName:key it will be added to existing document and result will be:

{
    keyName: key,
    valueName: value,
    valueName1: value1
}

Result will be:

• If there where no such keyName:key yet:

{
  "response": "inserted"
}

• If keyName:key already exists but doesn't have valueName provided:

{
  "response": "updated"
}

• If such keyName:key and valueName combination already exists and checkbox "Update if exists?" checked:

{
 "response": "updated"
}

• If such keyName:key and valueName combination already exists and checkbox "Update if exists?" not checked:

{
 "response": "skipped"
}

Store Batch

Inserts Key:Value pair array.

Input fields:

keyName - Name of a field where key will be stored

valueName - Name of a field where value will be stored

keyValArray - Array with values

Each value in array is object which have following fields:

keyValue - Value of a key that uniquely identifies Key:Value pair

value - Value that will be stored and can be accessed with provided keyName

Request example:

{
    keyName: "someKeyName",
    valueName: "someValueName",
    keyValArray: [
        {
            keyValue : "someKeyValue1",
            value: "someValue1"
        },
        {
            keyValue : "someKeyValue2",
            value: "someValue2"
        }
    ]
}

All provided Key:Vale pairs will be inserted, if key already exist it will be replaced.

Response:

{
  "response": "done"
}

Retrieve

Returns value by provided key and Value name if found or provided default value.

Input fields:

keyName - Name of a field where key is stored

key - Value of a key that uniquely identifies Key:Value pair

In response document from MongoDB collection will be provided, e.g.:

{
    keyName: keyValue,
    valueName: value,
    valueName1: value1
}

Retrieve Batch

Returns array of values by provided key array.

Input fields:

keyName - Name of a field where key stored

keyArray - Array of keyValues

Response format is following:

{
  "response": [
    {
      keyName1: key1,
      valueName1: value1
    },
    {
        keyName2: key2,
        valueName2: value2
    }
  ]
}

Remove

Removes Value provided in valueName or all values for specified key if "Delete all values for this key?" checkbox checked.

Input fields:

keyName - Name of a field where key stored

key - Value of a key that uniquely identifies Key:Value pair

valueName - Name of a field that should be deleted

Response format is following:

{
  "result": "done"
}
