URI Request Parameters

The request uses the following URI parameters.

environmentId

A unique identifier for the kdb environment.

Length Constraints: Minimum length of 1. Maximum length of 32.

Pattern: ^[a-z0-9]+$

Required: Yes

Request Body

The request accepts the following data in JSON format.

azMode

The number of availability zones you want to assign per cluster. This can be one of the following

  • SINGLE – Assigns one availability zone per cluster.

  • MULTI – Assigns all the availability zones per cluster.

Type: String

Valid Values: SINGLE | MULTI

Required: Yes

clusterName

A unique name for the cluster that you want to create.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 63.

Pattern: ^[a-zA-Z0-9][a-zA-Z0-9-_]*[a-zA-Z0-9]$

Required: Yes

clusterType

Specifies the type of KDB database that is being created. The following types are available:

  • HDB – A Historical Database. The data is only accessible with read-only permissions from one of the FinSpace managed kdb databases mounted to the cluster.

  • RDB – A Realtime Database. This type of database captures all the data from a ticker plant and stores it in memory until the end of day, after which it writes all of its data to a disk and reloads the HDB. This cluster type requires local storage for temporary storage of data during the savedown process. If you specify this field in your request, you must provide the savedownStorageConfiguration parameter.

  • GATEWAY – A gateway cluster allows you to access data across processes in kdb systems. It allows you to create your own routing logic using the initialization scripts and custom code. This type of cluster does not require a writable local storage.

  • GP – A general purpose cluster allows you to quickly iterate on code during development by granting greater access to system commands and enabling a fast reload of custom code. This cluster type can optionally mount databases including cache and savedown storage. For this cluster type, the node count is fixed at 1. It does not support autoscaling and supports only SINGLE AZ mode.

  • Tickerplant – A tickerplant cluster allows you to subscribe to feed handlers based on IAM permissions. It can publish to RDBs, other Tickerplants, and real-time subscribers (RTS). Tickerplants can persist messages to log, which is readable by any RDB environment. It supports only single-node that is only one kdb process.
