Ingest 500,000+ events per second and run sub-second OLAP queries over billions of rows by hiring freelance Golang programmer Aldian Fazrihady for ClickHouse. Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.

1. Production Architecture: Batched Async ClickHouse Native Protocol Ingestion & Materialized Views in Go

package analytics

import (
	"context"
	"github.com/ClickHouse/clickhouse-go/v2/lib/driver"
)

type APIEvent struct {
	TenantID   string
	Endpoint   string
	StatusCode uint16
	LatencyMs  uint32
}

func FlushBatch(ctx context.Context, conn driver.Conn, events []APIEvent) error {
	batch, err := conn.PrepareBatch(ctx, "INSERT INTO api_events (tenant_id, endpoint, status_code, latency_ms)")
	if err != nil {
		return err
	}
	for _, ev := range events {
		if err := batch.Append(ev.TenantID, ev.Endpoint, ev.StatusCode, ev.LatencyMs); err != nil {
			return err
		}
	}
	return batch.Send()
}

2. Core Architectural Guarantees

• Columnar Compression & Partitioning: Achieving 12x–18x ZSTD storage compression with `MergeTree` ordering keys tailored to tenant query patterns.
• Incremental Materialized Views: Pre-aggregating hourly and daily billing/analytics rollups automatically at insert time.
• Ring-Buffered Go Batchers: Protecting ClickHouse from small-insert part explosion by batching 10,000–50,000 rows per native TCP flush.
