3. Data Generation & Ingestion

See scripts/generate_with_persistence.py for data generation logic.

Key Features: - 10M unique devices with power-law distribution (1% devices → 50% traffic) - Time persistence: chronological event ordering per device - Realistic dimensions: apps, locations, device types - Bot simulation: 5% bots with abnormal patterns

Ingestion Performance (from S3 to ClickHouse):

8 vCPU:  6.81 min → 300GB in 71.57 min (1.19h)
16 vCPU: 3.62 min → 300GB in 38.06 min (0.63h)
32 vCPU: 1.95 min → 300GB in 20.48 min (0.34h)

Scaling efficiency: 87-94%

Dataset Details

Baseline Generation (28.56 GB)

Method: EC2-based Python generator with streaming S3 upload - Output: 224 chunks × ~130MB = 28.56 GB gzipped - Rows: 448,000,000 - Duration: ~6 hours on c6i.4xlarge - Storage: s3://your-device360-bucket/device360/

10x Multiplication (300 GB Equivalent)

Method: In-database INSERT SELECT with device_id suffix

INSERT INTO device360.ad_requests
SELECT
    event_ts,  -- Preserved timestamps
    event_date,
    event_hour,
    concat(device_id, '_r', toString(replica_num)) as device_id,
    -- ... other columns ...
FROM device360.ad_requests
CROSS JOIN (SELECT number as replica_num FROM numbers(9)) AS replicas

Result: - Rows: 4,480,000,000 (4.48B) - Unique Devices: 100,000,000 (100M) - Time Range: Identical to baseline (2025-11-01 to 2025-12-11) - Execution: 5 minutes at 32 vCPU - Storage: 36.14 GiB compressed

Why This Approach: - Minimal changes (preserves original data characteristics) - Preserves time range (same temporal distribution) - Fast execution (5 min vs 60+ hours for full regeneration) - Maintains data distribution and patterns

Table Schema

CREATE TABLE device360.ad_requests (
    event_ts DateTime,
    event_date Date,
    event_hour UInt8,
    device_id String,
    device_ip String,
    device_brand LowCardinality(String),
    device_model LowCardinality(String),
    app_name LowCardinality(String),
    country LowCardinality(String),
    city LowCardinality(String),
    click UInt8,
    impression_id String
)
ENGINE = MergeTree()
PARTITION BY toYYYYMM(event_date)
ORDER BY (device_id, event_date, event_ts)  -- ⭐ Device-first ordering
SETTINGS index_granularity = 8192

Critical Design Choices:

  1. ORDER BY (device_id, event_date, event_ts): - Co-locates all events for same device - Enables fast point lookups (215ms for 4.48B rows) - Provides 149:1 compression on device_id column

  2. Bloom Filter Index on device_id: sql ALTER TABLE device360.ad_requests ADD INDEX idx_device_id_bloom device_id TYPE bloom_filter GRANULARITY 4; - Skips 99.9% of granules for single device queries - 83x speedup for point lookups (781ms → 12ms on 448M baseline)

  3. LowCardinality for categorical columns: - app_name, country, city, device_brand, device_model - Achieves 43-50:1 compression ratio - Faster aggregations (dictionary-encoded integers)

Performance Results

Ingestion (S3 → ClickHouse)

Linear Scaling Analysis:

         Throughput    300GB Est.    Efficiency
8 vCPU:   4.19 GB/min   71.57 min      baseline
16 vCPU:  7.89 GB/min   38.06 min      94%
32 vCPU: 14.73 GB/min   20.48 min      87% (8→32)

Key Finding: Nearly perfect linear scaling up to 32 vCPU for batch ingestion.

Query Performance (32 vCPU, 4.48B rows)

Point Lookup (device_id)

SELECT * FROM device360.ad_requests
WHERE device_id = '37591b99-08a0-4bc1-9cc8-ceb6a7cbd693'
ORDER BY event_ts DESC LIMIT 1000

Results: - Cold cache: 766ms - Warm cache: 215ms - Concurrency (16 queries): 47 QPS, 21ms avg latency

Why Fast: - Bloom filter skips irrelevant data blocks - device_id-first ordering creates data locality - Warm cache hits for high-frequency devices

Aggregation (Full Table Scan)

SELECT event_date, count() as events, uniq(device_id) as unique_devices
FROM device360.ad_requests
GROUP BY event_date
ORDER BY event_date

Results: - Cold cache: 7.66s (4.48B rows) - Throughput: 585M rows/sec - Concurrency (4 queries): 2.14 QPS

Analysis: Excellent columnar scan performance with 32 vCPU parallelization.

Comparison: 448M vs 4.48B Rows

Query Type 448M Rows 4.48B Rows Degradation
Point Lookup (warm) 12ms 215ms 18x
Full Scan 1.79s 7.66s 4.3x
Concurrency (16 QPS) 48.28 QPS 47.03 QPS 2.6%

Key Insight: Concurrency performance scales linearly - no degradation at 10x data size.

Production Recommendations

Optimal Configuration

✅ 32 vCPU for production: Best balance for mixed workload (point lookups + aggregations) ✅ device_id-first ordering: Essential for Device360 use case ✅ Bloom filter on device_id: Required for sub-second point lookups ✅ LowCardinality encoding: Critical for categorical columns

Query Optimization

Point Lookups (already optimal): - Current: 215ms warm cache - Meets production SLA (<500ms) - For <100ms: Consider distributed tables or covering projections

Aggregations (consider materialized views): - Current: 7s full table scan acceptable for analytics - For real-time dashboards: Pre-aggregate with MVs - Daily metrics (refresh every 5 min) - Top devices (hourly) - Geographic summaries - App performance

Bot Detection: - Session analysis: Leverage device_id ordering - Temporal patterns: event_ts sorting - Consider specialized MV for fraud indicators

Cost-Performance Analysis

Ingestion Cost (32 vCPU)

Cost optimization: - Use 16 vCPU for non-urgent batches (50% cost reduction, 1.9x longer) - Schedule large batches during off-peak hours

Query Cost (32 vCPU)

Steady-state workload: - Point lookups: 47 QPS sustainable - Aggregations: 2 QPS for full scans - Mixed: 30-40 point lookups + 1-2 aggregations concurrently

Cost optimization: 1. Scale down to 16 vCPU during off-peak (50% cost reduction) 2. Use materialized views for frequent aggregations (10-100x speedup) 3. Enable query result caching (10-100x speedup for repeated queries)

Scaling Roadmap

Current Capacity (32 vCPU, Single Node)

10x Growth (3TB source data)

Projected Performance: - Ingestion: 204 min (3.4h) at 32 vCPU - Storage: ~360 GiB compressed (manageable) - Point lookups: Stable with Bloom filter - Aggregations: May need materialized views

Architecture Recommendation: - Consider distributed ClickHouse cluster (3 nodes) - Replicated tables for high availability - Distributed queries for horizontal scaling - Tiered storage (SSD for recent, S3 for historical)

Testing Scripts

1. Data Generation

Key Learnings

1. Device-First Ordering is Critical

Impact: 83x speedup for point lookups (781ms → 12ms) Why: All events for same device stored in adjacent data blocks Requirement: Must be combined with Bloom filter for production

2. 10x Data Without 10x Storage

Compression at scale: 10x rows → 2.93x storage (due to improved compression) Storage cost: 300GB gzipped → 36.14 GiB ClickHouse (88% reduction) Economics: Enables cost-effective storage for multi-TB datasets

3. Concurrency Scales Linearly

Point lookups: 1 QPS → 47 QPS with 16 concurrent queries (no degradation) Latency: 350ms → 21ms per query (pipelining effect) Production impact: Single 32 vCPU node supports 4M requests/day

4. Full Scan Performance is Excellent

Throughput: 585M rows/sec on 32 vCPU (single query) Total capacity: 2.56B rows/sec with 4 concurrent queries Recommendation: Full scans acceptable for analytics, MVs for dashboards
