Why caching & optimisation matter for high-volume football APIs
When running a football data service at scale which covers many leagues and handles many simultaneous users, relying on a fresh API call for every user request is not sustainable. Caching and intelligent API-call optimisation become very important.
Performance & latency
– Near-instant response: Each time you fetch data from the server, you add to the overall delay (latency) due to network travel and processing costs. For a live football app, where thousands of users may refresh a match widget at once, every millisecond counts.
– A well-placed cache stores frequently requested data closer to the user, allowing a multi-second API response to be delivered almost instantly, dramatically improving the user experience.
Server/backend load and cost
– Without caching, every single user action translates into a fresh API call, which then requires compute power and a database hit. This multiplies rapidly with a growing user base.
– Reduced cost: Caching avoids hitting the backend database or your external data provider for every repetitive request. This lowers your operational cost and frees up backend capacity to focus on handling the truly dynamic, unique parts of your service.
Rate limiting & stability
– Most sports data providers impose rate limits (e.g., a certain number of requests per hour) to protect their infrastructure and ensure fair access.
– Caching helps you stay under these limits by serving repeat or similar requests directly from your local cache instead of making a new call to the provider every time.
– More broadly, caching helps to absorb traffic spikes such as when a major match starts or a goal is scored which ensures your system remains stable instead of crashing under sudden heavy load.
Freshness vs. stability trade-off
– A core challenge in sports data is balancing the need for freshness (real-time events) against the need for stability (handling massive load). Not all data changes every second.
– Designing your strategy involves deciding which endpoints require high freshness (e.g., live events) and which can be safely cached for a few minutes (e.g., static fixture lists or league tables) using a Time-To-Live (TTL) mechanism. This trade-off is central to creating an efficient and reliable application.
Key caching and optimisation strategies for football APIs
When you’re building a high-volume football data integration, you need specific strategies to manage traffic. Relying solely on raw API calls or simple caching won’t work at scale.
Choosing what to cache
The first step is deciding which data is worth caching based on how often it changes and how frequently it is requested:
– High cache priority: Endpoints that change rarely, such as historical match results, past league tables, or season fixture lists from last year, are excellent candidates for caching.
– Low/no cache priority: Live events (goals, cards, substitutions) need very short Time-To-Live (TTL) or should bypass the cache at the user-facing layer entirely.
– Medium priority: Data like a mid-season league table might be safely cached for 5 minutes, while a player’s static profile can be cached for several hours.
Caching locations and layers
Deploying caching at multiple points gives you flexibility and resilience:
– Client-side caching (browser/mobile): Useful for static assets (logos, player photos) or endpoints that users revisit often, like the “next 5 upcoming matches” list.
– Server-side / in-memory caching (e.g., Redis): Ideal for high-traffic endpoints where you want to serve many users from one cached result, dramatically reducing upstream API calls.
– Reverse proxies / CDN / edge caching: Great for users accessing your API globally, especially for pre-match metadata that doesn’t need strict, second-by-second freshness.
Use of filters, includes & payload minimisation
To get more than just the benefit of caching, reduce the amount of data you ask for:
– Payload filtering: Use API features to request only the fields you actually need (e.g., just the player’s name and number, not their entire career history).
– Avoid large payloads: Smaller requests mean less memory usage, faster response times, and better cache hit rates.
– Use includes sparingly: Fetch related data via a single endpoint using includes (e.g., fixture?include=lineups,events) rather than making multiple separate API calls.
TTLs, invalidation & freshness strategy
– Set appropriate TTLs: The lifespan of cached data must reflect its volatility. Historical data can have TTLs of days, while a match preview might be cached for 60 minutes.
– Invalidation: For live updates, set up an invalidation mechanism. When an event like a goal or red card occurs, you should actively clear or update the relevant cache keys so you don’t serve old data.
Reducing bandwidth & API call volume
– Combine requests: Fetch related data via one endpoint rather than hitting many endpoints repeatedly.
– Smart pagination: Only fetch pages of a large list that are currently being displayed to the user.
– Compression: Enable compression (e.g., gzip or Brotli) on your responses to significantly reduce payload size and bandwidth. This aligns with the need to reduce API bandwidth.
Monitoring, metrics & cache hit rates
You need to measure the effectiveness of your strategy:
– Cache hit rate: Track the percentage of requests that are served from your cache versus those that require a call to the upstream provider.
– Upstream API call volume: Monitor the number of calls you make to your provider to ensure you’re staying under budget.
– Latency improvements: Measure how much faster responses are when served from the cache.
If your cache hit rate is low, your TTLs might be too short, or you might be caching endpoints that users rarely access.
Managing rate limits via caching & optimisation
– Rate limit buffer: Caching directly protects you from hitting rate limit thresholds by serving many requests from your cache instead of using up your provider calls.
– Stability: In high-volume scenarios (big match, many users), caching acts as a buffer, preventing your system from being throttled or blocked by sudden load spikes.
Applying to football API usage (real-world architecture example)
Taking the theories of caching and optimisation into a real-world football data context helps anchor what you should actually build. Here is a sample architecture and workflow you could adopt when integrating a Football API at high volume.
Sample high-volume workflow
When a user opens a live match detail page:
- Client request: Your application receives a request for the match page (e.g., “Team A vs Team B”).
- Cache check: Your backend immediately checks its server-side cache (e.g., Redis) for a key like match:12345:details.
- Cache hit (if data is there): The match data is served instantly to the user, this is fast and has minimal latency.
- Cache miss (if data is missing): You call your upstream provider’s endpoint (e.g., /fixtures/12345?include=events,teams,players).
- Optimise fetch: You use includes/filters to fetch only the essential fields you need (team names, event list, player line-ups).
- Store and serve: You store the result in the cache with a short TTL (e.g., 30 seconds for a live match) and then serve the data to the user.
- Live update: When a real-time event happens (goal, red card), you actively invalidate or update the cache key so the next users see the latest update, rather than waiting for the 30-second TTL.
- Less volatile data: For things that change slowly (like the next fixture list or the full league table), you cache for much longer, maybe 5 or 30 minutes.
Architecture layers & design considerations
– Front-end / client:
– Leverage browser cache for semi-static data (team profiles, upcoming fixtures).
– Route all real-time data requests through your backend proxy to keep your API token secret and centralise your caching logic.
– As highlighted in best practices, never integrate the API token directly into the client-side (browser/mobile app).
Backend proxy / API gateway:
– This is the single entry point for your clients and is responsible for keeping your API key secure.
– It implements your caching layer (Redis) and manages the logic for TTLs, invalidation, and tracking cache metrics.
– It maintains rate-limit awareness, monitoring your cumulative API calls to the provider. By caching heavily, you reduce dependency on the upstream API and avoid exceeding provider limits.
– Upstream provider integration:
– Use provider endpoints efficiently: always apply includes/filters to limit the size of the data package and use pagination correctly for large lists.
– Cache static entities like “continents” or “types” that the provider recommends.
– Organise your system to have a buffer of available calls for peak match times.
– Cache & data layer:
– Partition cache keys by specific detail: e.g., league:34:standings, fixture:12345:events.
– Align TTLs with volatility: short TTLs for live events, long TTLs for static data.
– Monitor hit/miss ratios, latency improvements, and upstream call reductions. Use this data to tune your TTLs and layering strategy.
Example: Reducing bandwidth & call-count in a live match scenario
Imagine a busy match with thousands of users refreshing the event feed. Without optimisation, each user’s request would trigger a separate call to the upstream API every few seconds, resulting in a huge number of API calls and a high risk of being throttled.
With optimised architecture:
– Your backend caches the match events for, say, 15 seconds.
– All user requests within that 15-second window hit the cache (no upstream call is made).
– You might use compression (gzip) and filters to only send the latest events, not the full history, further reducing bandwidth.
– Only on key event triggers (goal, red card) do you invalidate the cache or push an update to clients.
– This can reduce upstream API calls by perhaps 90% (e.g., only 1 call every 15 seconds instead of potentially dozens), which substantially reduces bandwidth and rate-limit consumption.
How to roll this out practically
- Map endpoints: List all the API endpoints you plan to use. For each, decide on its volatility (how often it changes) and access-frequency (how often users will request it).
- Define caching rules: For each endpoint, set a TTL or an invalidation rule and create a cache key naming convention.
- Instrument metrics: Start tracking essential metrics: request rates, cache hit/miss ratio, payload sizes, and upstream call count.
- Deploy and configure: Set up your caching layer (Redis) and configure your backend code to check the cache before calling the provider.
- Monitor spikes: During a real match-day spike, monitor your system to ensure your cache hit ratio is high, your upstream call count is low, and your latency is stable. Tune your strategy based on these results.
Using Sportmonks in context
When you choose a provider like Sportmonks for a high-volume football application, you get the architectural support and flexibility needed to run an effective caching and optimisation strategy.
Sportmonks API overview
Sportmonks offers a football API covering over 2,500 leagues globally, with live scores, line-ups, events, and statistics. The platform is designed to be developer-friendly, with clear documentation and flexible plans. For high-volume scenarios, Sportmonks provides features and best practices that directly support caching and optimisation.
Built-in optimisation features
Includes & filters: These let you fetch only what matters. Instead of pulling entire datasets, you can request targeted data such as specific match events or selected player fields.
Example: &include=events:player_name,minute;events.type&filters=eventTypes:18,14
This fetches only goal or substitution events, reducing payload size and speeding up delivery.
Initial data load and pagination: Sportmonks supports filters=populate and idAfter to streamline large imports.
– filters=populate disables includes and allows larger page sizes (up to 1000 records), reducing the total number of requests.
– idAfter lets you fetch only new or updated records, keeping your local database in sync without re-fetching everything.
Reducing includes and response data: Our documentation recommends caching static reference entities such as:
– States
– Types
– Continents
– Countries
– Regions
– Cities
Caching these entities dramatically cuts the number of includes in subsequent requests. Since these change rarely, you avoid repeatedly downloading identical data, which can reduce your request volume by up to 50 percent. In short: cache what barely changes (like countries or types) so you can focus live calls on dynamic data (like fixtures or match events).
Rate-limit transparency: Sportmonks openly lists its API rate limits and encourages client-side throttling. By combining this with caching, you stay well below usage caps, ensuring reliable service even during traffic spikes.
How you integrate caching + optimisation with Sportmonks
Here’s how you can build your high-volume system using Sportmonks:
– Design efficient requests: Use includes and filters to trim responses. Fetch only necessary relationships and limit fields.
– Cache stable entities: Entities like Types or Countries rarely change. Store them locally or in-memory to eliminate redundant includes.
– Use caching layers for traffic absorption – A Redis or CDN layer prevents spikes from hitting the upstream API. Serve cached data during high-load match windows.
– Synchronise smartly: Use idAfter to update your local database incrementally rather than re-pulling entire datasets.
– Monitor and iterate: Track cache hit rates, payload sizes, and upstream call counts. Adjust TTLs based on volatility: longer for static data, shorter for live feeds.
Benefits for a high-volume scenario
Not every dataset benefits equally from caching:
– Static entities (e.g., countries, types, cities) almost never change, so long TTLs or permanent caching make sense.
– Semi-static entities (e.g., teams, leagues) change infrequently, cache for hours or days.
– Dynamic entities (e.g., fixtures, standings) need shorter TTLs or update triggers when a match finishes or data changes.
– Live entities (e.g., match events, line-ups) are best handled with short-term caching or real-time updates.
By classifying entities this way, you reduce unnecessary includes and ensure bandwidth is spent only where freshness matters.
Example integration snippet
Here’s a short example of how you might implement a high-volume workflow:
// Requesting fixture events GET https://api.sportmonks.com/v3/football/fixtures/12345 ?api_token=YOUR_TOKEN &include=events:player_name,minute;events.type &filters=eventTypes:18,14 // Cache the response under key “fixture:12345:events” with TTL = 15 sec // Serve user requests within TTL from cache // On new event (goal/sub) arrive via webhook or polling → invalidate or update cache
In this scenario, your clients (many users) act against your cache layer instead of constantly hitting the Sportmonks API.
