# variables for terraform, ansible
# configure 
#  bastion hosts, mgmt instances
#  db connection attributes
#  os images  
#  network parameters, storage
#

### Instance configuration
# Creating an NxK TimesTen Scaleout Cluster (default 2x2)
# Creates VCN, subnets, compute resources
# The N in NxK (replica sets)
variable  "diInstanceCount" { default = "2" }

# Compute instance shape for data instances
# N*K VMs/BMs are provisioned for data instances
# Not allowed to use VM.Standard1.1 shape
# Recommended to use NVMe shape (DenseIO, HighIO) for best performance
variable  "diInstanceShape" { default = "VM.DenseIO1.4" }

### K-Safety
# The K in NxK (copies of data)
# Supports {1|2}
# By default, K==2 spans ADs; see singleAD variable below
variable  "ksafety" { default = "2" }

# ZooKeeper is allocated on zkInstanceCount VMs
# To co-locate Zk VMs with mgmt/data VMs set zkInstanceCount=0
# Otherwise set zkInstanceCount=3 for stand-alone VMs
variable  "zkInstanceCount" { default = "0" }
variable  "zkInstanceShape" { default = "VM.Standard1.1" }

# Number of hosts for mgmt instances {0|2}
# 0 = co-located with data instance VMs
variable  "mgInstanceCount" { default = "0" }
variable  "mgInstanceShape" { default = "VM.Standard1.1" }

# Client only installations are allocated on clInstanceCount VMs
# clients are provisioned on private subnet
variable "clInstanceCount" { default = "0" }

# Number and shape of Bastion hosts {1|2|3}
variable  "bsInstanceCount" { default = "1" }
variable  "bsInstanceShape" { default = "VM.Standard1.1" }

### Which AD(s)
# Compute instances provisioned round robin to AD mod ksafety
# To start provisioning in AD3, initialAD=3
# Valid values are 1-3 otherwise 1 is used
variable  "initialAD" { default = "1" }
# Co-locate data spaces and management instances in same AD
# singleAD == { "true" | "false" }
variable  "singleAD"   { default = "false" }

### Block Volumes if any
# One block volume for each data compute instance (NxK)
# To use block volumes, instance shape must be standard
# If both block and nvme devices exist, DB is created on nvme only
#
# Size of block volume in GB to attach to each data compute instance
# diBlockVolumeSizeGB < 50 means do not attach block volumes to any data compute instance
# Minimum allocation is 50 GB
variable "diBlockVolumeSizeGB" { default = "0" }
