Summary

  • Increases the default clickhouse.chgo.maxConns from 8 to 32
  • 78 table writers share a single connection pool — the old default of 8 caused unnecessary pool contention during concurrent flush bursts
  • 32 gives comfortable headroom (~40% of routes) without risking ClickHouse max_concurrent_queries limits across replicas
  • Updates tests, docs, and example config to match

78 table writers share a single connection pool. The old default of 8
was too low for concurrent flush bursts, causing unnecessary pool
contention. 32 gives comfortable headroom without risking ClickHouse
max_concurrent_queries limits across replicas.
