# We set up a file descriptor to redirect input/output from bash's tcp pseudodevice
# This allows us to, for example, call Zookeeper 4lws without needing netcat
# Works everywhere that bash works (proven on RHEL 7.x, AIX, MacOS bash 3.2)

# Purpose: 
#   This script wraps curl with caroot, cert and key files obtained from the standard
#   /var/ssl/private folder used by cp-ansible for deployed Confluent Platform components.
#   The idea is to allow you to get on with hitting the Schema Registry REST endpoing
#   without faffing around providing repetitive cert args.
#   Does some super basic checks if we are registering Schemas on SR and provides the

# Purpose: 
#   This script uses the linux traffic control `tc` command to add delay, drop packets, etc
#   which is useful when we want to test software behaviour under stress conditions, e.g.
#   such as spiking latency between Zookeeper or Kafka nodes, simulating a data centre outage
#   or restricting bandwidth between components to simulate inter-DC resource contention.

# Purpose: Increase the replication factor of one or more topics, using only
#          a connection to the Kafka broker (no Zookeeper, REST APIs etc)
#          and the standard kafka-topics, kafka-reassign-partitions scripts
#          that come with Kafka.

# Purpose: Let's use Kafka CLI tools to get topic counts.
#   This should be usable on any Kafka install since it uses 
#   only the kafka-consumer-groups utility and some standard
#   unix tools to sum up.
