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.
