# Development Property Sharding Example
# This example is optimized for development and testing environments
#
# DEVELOPMENT NOTES:
# - Requires at least 2 servers (3+ recommended for HA)
# - Uses minimum viable resource allocation (4GB memory, 2 CPU cores)
# - Suitable for learning, testing, and small-scale development
# - NOT recommended for production workloads
# - Consider using regular Neo4j clusters for basic development
#
# ALTERNATIVE: For pure development without property sharding features,
# use examples/clusters/development-cluster.yaml instead

# Prerequisites: Create admin secret (REQUIRED)
# kubectl create secret generic neo4j-admin-secret \
#   --from-literal=username=neo4j \
#   --from-literal=password=dev-password
