TL;DR
Real-time processing handles data as it arrives, producing results within seconds; batch processing accumulates data over time (minutes, hours, daily) and processes it in bulk. iGaming operators use both, matched to specific use cases: real-time for fraud detection, trading, RG intervention, live personalisation; batch for reporting, ML training, financial close and most CRM. Understanding when each fits matters because building real-time infrastructure for problems that batch would solve wastes engineering effort and money; using batch for problems that need real-time creates operational gaps. This is the closing entry of the iGaming Glossary.
How each processing model works
Real-time (streaming) processing:
- Data flows continuously as events happen: bets, deposits, sessions, wallet updates.
- Processing infrastructure (Kafka, Pub/Sub, Kinesis, Flink) handles events with latencies of milliseconds to seconds.
- Output can trigger immediate actions: block a fraudulent transaction, adjust an odds market, send an RG intervention.
- Complexity is higher: exactly-once semantics, event ordering, late-arriving data, stateful processing.
- Infrastructure cost is generally higher per event processed than batch.
Batch processing:
- Data accumulates over defined windows (5 minutes, 1 hour, daily) before processing.
- Processing runs as scheduled jobs or event-triggered tasks (dbt, Airflow, Dataflow).
- Output feeds dashboards, reports, ML training, downstream operational systems.
- Complexity is generally lower: batch semantics are simpler than streaming.
- Infrastructure cost per event is generally lower than real-time.
The right choice per use case depends on latency requirements:
- Real-time (<1 second): trading price adjustments, immediate fraud blocking, real-time RG intervention on active session.
- Near real-time (1 second to 1 minute): live segmentation for CRM, in-game personalisation, real-time dashboards for operations.
- Frequent batch (5 minutes to 1 hour): trading analytics, refresh of active dashboards, real-time-ish reporting.
- Hourly batch: most operational BI, most CRM analytics, marketing performance.
- Daily batch: financial close, regulatory reports, ML training, executive dashboards.
Why the choice matters in iGaming
iGaming has specific use cases where real-time genuinely matters: sportsbook trading during events, fraud detection at the transaction moment, RG intervention on active sessions, in-game recommendation for live experience. It also has many use cases where batch is fine and real-time would be overkill: monthly finance reporting, CRM campaign analysis, historical trend review. Operators that build real-time infrastructure for every problem overspend; operators that build only batch when real-time is needed create operational blind spots.
Different teams face different real-time requirements:
- Trading needs real-time for active in-play markets.
- Fraud needs real-time for blocking bad transactions before they complete.
- Compliance sometimes needs real-time (RG intervention) and sometimes batch (regulatory reports).
- CRM usually works with batch except for specific real-time triggers.
- Finance uses batch for close, real-time for cash-flow monitoring.
- BI mostly uses batch with occasional real-time dashboards.
- Executives care about outputs, not the underlying processing model.
Modern architectures typically combine both: real-time event streams feeding both immediate use cases and batch pipelines that materialise the streams into analytical tables. This lambda-style pattern (or its evolution, kappa architecture) gives operators the flexibility to add use cases without re-architecting.
Common mistakes and how operators mismatch processing to use cases
Real-time everything. Some operators build real-time infrastructure for use cases that batch would solve. This produces higher costs, more complexity and no operational advantage. Real-time should be justified by specific latency requirements, not treated as default.
Batch when real-time is needed. The opposite mistake: relying on daily or hourly batch when fraud detection, trading or RG intervention need real-time. Batch-only architectures produce operational gaps.
Real-time without downstream real-time. Building real-time pipelines that feed batch dashboards produces expense without benefit: the real-time processing produces no faster outcome because the consumer refreshes hourly anyway. End-to-end real-time only pays back when downstream consumption is also real-time.
No exactly-once semantics. Real-time systems processing wallet transactions, bets or other financially-consequential events need exactly-once semantics. Systems allowing duplicate or lost events produce reconciliation issues and player disputes.
Late-arriving data ignored. Real-time systems must handle events arriving after their expected window (network delays, mobile disconnects). Systems assuming perfectly-ordered events produce quality issues under real-world conditions.
Complexity underestimated. Real-time infrastructure is meaningfully harder to operate than batch. Teams new to real-time often underestimate the operational burden: monitoring, incident response, capacity planning. Adopting real-time requires organisational capability, not just technology choice.
Batch pipelines run too slowly. Some operators run daily batch jobs that complete late in the following business day, effectively making yesterday's data unavailable when it is needed. Faster batch (multiple daily runs, hourly refresh) often provides better operational value than pursuing real-time.
What good architecture looks like
Practices observed in operators with well-matched processing:
- Real-time for the specific use cases (trading, fraud, RG) that need it.
- Batch for most analytics with cadences matching consumption patterns.
- Combined architectures where real-time events feed batch materialisation.
- Exactly-once semantics on financially-consequential real-time processing.
- Explicit handling of late-arriving events in real-time systems.
- Batch cadence optimised for actual downstream needs, not tradition.
- Clear decision framework for evaluating new use cases against processing models.
How Gamblitude handles both models
Gamblitude combines both processing models matched to iGaming use cases. Event ingestion uses streaming infrastructure feeding both immediate real-time consumers (trading dashboards, fraud detection, RG intervention) and batch materialisation into the warehouse. Most analytical dashboards, reports and metric computations run on batch refresh cadences appropriate to the use case (hourly for operational metrics, daily for executive reporting). Insight Radar can operate on either real-time signals or batch outputs depending on the check. AI Agent queries governed metrics that are typically batch-materialised, giving consistent answers rather than fluctuating real-time responses. Operators do not need to choose between real-time and batch as an architectural philosophy; they get both matched to the specific use case.
FAQ
Usually no, at least not entirely. Most data warehouse use cases (reporting, analytics, ML training) tolerate hourly or daily refresh. Building a fully real-time warehouse is expensive and rarely produces proportionate value. Combining real-time event streams for specific use cases with batch warehouse materialisation is the standard modern pattern.
Streaming is the technical pattern (continuous event processing); real-time is the outcome (results within seconds of event occurrence). Streaming enables real-time processing but can also feed near-real-time or batch downstream. All real-time systems in modern architectures are typically streaming underneath; not all streaming systems produce real-time output.
Depends on scale and use case. Kafka is popular for streaming event backbones. Cloud alternatives (Google Pub/Sub, AWS Kinesis, Azure Event Hubs) serve similar purposes with managed operations. Smaller operators sometimes use simpler queue systems. The choice depends on scale, cloud strategy and operational preference.
Materially more than batch per event processed, but the total cost depends on volume and complexity. Real-time infrastructure has base costs that make it expensive at low scale and increasingly efficient at high scale. Operators considering real-time should model total cost of ownership including operational burden, not just infrastructure cost.
Sometimes yes, sometimes no. 5-minute batch is fast enough for many use cases previously considered real-time. But fraud blocking, trading, RG intervention on active session genuinely need sub-second latency that batch cannot provide. Evaluating whether faster batch would work before committing to real-time is worth the effort.
