summary
Talk describes AdequateRecord, a fork of ActiveRecord that introduces bind-parameter caching and a statement cache, yielding up to ~100% faster SQL generation, 70% fewer allocations and near constant-time has_many :through growth for deep joins. Benchmarks use benchmark/ips and GC.stat; experiments show ~30% speed for cached where queries while find_by stays ~3x faster than equivalent where calls. Trade-offs are increased memory (cache size ≈ relations+find_bys × entry size) and API complexity.
