# Example ITRS Analytics configuration for AWS EC2 handling 250k Obcerv entities and 100k metrics/sec, and 100k OpenTelemetry
# spans/sec (pre-sampling).
#
# Nodes:
# - (2) m5.8xlarge (32 CPU, 128GiB Memory) for Timescale
# - (6) c5.4xlarge (16 CPU, 32GiB Memory) for all other workloads
#
# The resource requests for Timescale total 48 cores and 360GiB memory.
# The resource requests for the other workloads total ~59 cores and ~134GiB memory.
# These totals include Linkerd resources.
#
# Disk requirements:
# - Timescale:
#   - 4 x 2 TiB timeseries data disk for each replica (x2)
#   - 200 GiB data disk for each replica (x2)
#   - 300 GiB WAL disk for each replica (x2)
# - Kafka broker: 400 GiB for each replica (x3)
# - Kafka controller: 1 GiB for each replica (x1)
# - Loki: 30 GiB
# - etcd: 1 GiB for each replica (x3)
# - Downsampled Metrics:
#   - Raw: 5 GiB for each replica (x4)
#   - Bucketed: 5 GiB for each replica (x4)
#
# The configuration references a default storage class named `gp3` which uses EBS gp3 volumes. This storage class should
# be configured with the default minimum gp3 settings of 3000 IOPS and 125 MiB/s throughput.
#
# The configuration also references a storage class named `gp3-timescale` which uses EBS gp3 volumes, but with
# higher provisioned performance for the WAL volumes. This storage class should be configured with 5000 IOPS and
# 200 MiB/s throughput.
#
# You can create these classes or change the config to use classes of your own, but they should be similar in performance.
#
# This configuration is based upon a certain number of Obcerv entities, average metrics per entity, and
# average metrics collection interval. The following function can be used to figure out what type of load to expect:
#
# metrics/sec = (Obcerv entities * metrics/entity) / average metrics collection interval
#
# In this example configuration, we have the following:
#
# 100,000 metrics/sec = (250,000 Obcerv entities * 4 metrics/entity) / 10 seconds average metrics collection interval
#
# NOTE: Ingestion, storage, and retrieval of OpenTelemetry spans is a beta feature.
#
# Additionally, the configuration is based upon a certain number of OpenTelemetry spans per second that are sampled
# based upon the following rules:
# - Error traces are always sampled
# - Target sampling probability per endpoint (corresponds to the name of the root span) is 0.01
# - Target sampling rate / second / endpoint (corresponds to the name of the root span) is 0.5
# - Root span duration outlier quantile is 0.95. The durations of all root spans are tracked and used to make guesses about
#   abnormally long spans
