Hi C***a, Great,Wednesday, June 5 at 3:00 PM CET is confirmed. To address your questions: 1. Current headcount Our global Data & CRM organization is about 30 specialists strong,Data Analysts, CRM strategists, BI developers and Marketing Automation experts across EMEA, Americas and APAC. This role reports directly into the Chief Marketing Officer and sits on the global leadership team. 2. Analytics & automation platforms We run a best-in-class stack: - Web & mobile analytics: Google Analytics 360 and Adobe Analytics - BI & reporting: Microsoft Power BI - Marketing automation & campaign orchestration: Salesforce Marketing Cloud (with a few regional tools in select markets) We’ll dive deeper into how the team operates and our tech roadmap during our call. Looking forward to our conversation! Best regards, J***e HR Recruiter, StrategyBrain

Hi C***a, Great questions. Here’s a high-level view of how we currently handle it: 1. Centralized data lake (with a CDP layer on our roadmap) • We ingest GA360, Adobe Analytics and Salesforce MC data into a single cloud-based data lake. All web, mobile and campaign metrics flow through our ETL pipelines, giving us a unified customer profile. • Marketing Cloud interactions are stitched to analytics events via a common customer ID. This setup supports batch reporting today, and we’re piloting a lightweight CDP to enable real-time activation in key markets. 2. Regional data governance at scale • Hub-and-spoke model: our Global Data Governance Council defines taxonomy, privacy standards (GDPR, CCPA, etc.) and vendor controls. • Local stewards in EMEA, Americas and APAC tailor those policies to their markets, vet data sources and sign off on campaign use cases. • We enforce role-based access, encryption in transit/at rest, and automated compliance checks. This framework lets us roll out high-personalization campaigns quickly while keeping data quality and privacy front and center. I’d love to dive deeper into any of these areas on our call,let me know which topic you’d like to unpack first. Best, J***e

Hi C***a, Happy to unpack this. Here’s a high-level view of our approach: 1. Schema management • Central schema registry: every data source (GA360, Adobe Analytics, SFMC, etc.) pushes a JSON schema into our registry as part of the ingest process. • Version control & validation: schemas are versioned in Git; our ETL jobs pull the current version and automatically validate incoming payloads, enforcing consistent field names, types and contracts. • Evolution guardrails: when a source schema changes, we run compatibility checks (backward/forward) before deploying pipeline updates, so we never break downstream consumers. 2. Real-time stitching • Event streaming layer: we have a lightweight streaming bus that captures events from web, mobile and marketing systems in near real time. • Identity graph join: events are keyed on our universal customer ID, then merged into a “stitching” service that maintains a live, unified customer record. • Low-latency writes: stitched records land in our data lake ++ streaming store within seconds, making fresh profiles available for personalization engines. 3. Lightweight CDP pilot • Microservice-driven: the pilot runs as a small containerized service that subscribes to the streaming layer, hydrates core profile attributes (lifetime value, propensity scores, recent behaviors) and caches them in an in-memory store. • API-first activation: campaign and site-personalization tools call this service via a simple REST API to retrieve up-to-the-second customer data. • Focused scope: we’ve rolled it out in two markets so far, powering real-time cart abandonment emails and on-site product recommendations. It lives alongside our batch reports and feeds the same governance rules. Does this match the level of detail you’re looking for? I’d be happy to dive deeper into any piece,pipeline orchestration, data contracts or the CDP activation flow,either here or on our call. Best, J***e

Hi C***a, Great questions,here’s a bit more under the hood: 1. Streaming layer - We run Apache Kafka (self-managed on AWS MSK) as our primary event bus. - In EMEA/AMER/APAC we mirror topics across clusters with MirrorMaker for low-latency failover and cross-region consistency. 2. ETL orchestration - Apache Airflow orchestrates all of our schema-validated pipelines. - Each DAG imports the JSON/Avro schema from our central registry, runs a pre-flight validation task, then spins up Spark jobs (or Python workers) against the streaming batch. 3. Schema-drift detection & handling - We enforce compatibility rules in Confluent Schema Registry (backward/forward checks) before any deploy. - In Airflow we’ve built a “drift-watcher” operator that: • Compares incoming payloads to the registered schema, • Emits metrics to our observability dashboard, and • Triggers a Slack/JIRA alert if fields appear/vanish or types change beyond tolerance thresholds. - If a drift alert fires, the DAG will automatically pause downstream tasks, preserving the last known good output, and flag the schema change for the data-platform team to review and remediate. Does this level of detail help? Happy to unpack any part of the Kafka setup, our Airflow plugins or the drift-watcher logic on our call. Just let me know! Best, J***e

Hi C***a, Here’s some more color on our setup: 1. Kafka sizing & geo-redundancy • Cluster footprint: each region (EMEA, AMER, APAC) runs a 6-node AWS MSK cluster (across three AZs) with 100 GB EBS per broker. • Partition strategy: critical topics (events, profiles, campaign actions) have 50,100 partitions to parallelize throughput; lighter topics sit at 10,20. • Cross-region mirroring: we use MirrorMaker 2.0 to replicate key topics with end-to-end replication latencies typically under 200 ms. • Delivery SLAs: we target <1 second publish-to-subscribe for real-time streams and 99.9% uptime per region. 2. Airflow & Spark resource scaling • EMR-based clusters: our DAGs spin up dedicated EMR clusters with auto-scaling enabled (min/max Executors) based on YARN CPU/memory metrics. • Dynamic scaling: Spark jobs request container resources dynamically,clusters grow or shrink (20% scale step) to match workloads, then spin down to save cost. • Fixed vs. dynamic: latency-sensitive pipelines use a “warm” mini-cluster pool; batch/stream ops leverage fully auto-scaled EMR pools. 3. Drift-watcher observability & thresholds • Observability stack: metrics and schema-drift events flow into Datadog (custom dashboards + alerting) and Grafana; critical alerts push to Slack channels and PagerDuty. • Threshold calibration: we bootstrap tolerances from 95th-percentile field-presence metrics over a 30-day window and apply a 3σ rule for numeric changes. • Continuous tuning: data-platform engineers review drift alerts weekly, adjust thresholds per topic, and annotate root-cause fixes in JIRA. I hope this helps,let me know if you’d like to drill into any piece. If you’re ready, I can also set up a quick chat with our Data Platform Lead to explore these details further.

Hi C***a, Great questions,here’s the quick background on how we arrived at those numbers: 1. Kafka sizing & partitions • Throughput benchmarks: we ran load tests simulating our peak holiday traffic (roughly 150K events/sec). A 6-node MSK cluster with 100 GB EBS per broker gave us comfortable headroom for retention and compaction without impacting tail-latency. • Partition count: we found that 50,100 partitions on hot topics sustained ~3,5 K msgs/sec/partition across our consumer group, which kept end-to-end publish-to-consume latencies under one second even under burst. Lower-volume topics stayed at 10,20 partitions to balance parallelism vs. controller overhead. 2. EMR auto-scaling parameters • Min/max executors: for our real-time pipelines we keep a warm pool of 8 executors (to guarantee sub-second startup), scale up to 64 when utilization (CPU+memory) crosses a 65% threshold, and never exceed that to cap costs. • Scale-step sizing: we use 20% increments (roughly 1/5 of current executors) so clusters grow/shrink smoothly without thrashing. • SLA tuning: we monitor per-job latency in Datadog and target 0.7,0.9 s end-to-end. If we see any sustained drift (above 1 s), our auto-scale rules kick in more aggressively for the next run. Happy to share our benchmark reports or set up a quick session with our Data Platform Lead if you’d like more granular numbers. Let me know what works best for you! Best, J***e
