# For every connection, Amazon Keyspaces allows 3000 request per connection per endpoint
# If pool.local.size = 3 * 3 endpoints = 9 total connections for session
# For 9 connections at 3000 request per connection for a total of 27,000 rps
# Amazon Keyspaces supports up to 3000 CQL requests per connection per second.
# Public endpoints expose 9 peers: pool.local.size = 3 * 9 endpoints = 27 connections.
# VPC endpoints typically expose 2-5 peers (most commonly 3).
# At 500 requests/sec per connection (recommended), 27 connections support 13,500 rps.
