    Reasons for Scaling

    • Growing User Base
      • Popular games attract new users fast.
    • Seasonal Traffic
      • Increased transactions during events like major sporting events for online betting games or the launch of a new, hotly-anticipated game version.
    • Growing Datasets
      • High volume of writes and rapidly growing data volume as more users join. A growing user base means more microtransactions performed within the game.
    • New Geographies
      • Expanding the user base into new regions requires additional regions globally to provide low latency, and high availability to those users.
    YugabyteDB Scaling Capabilities
    • Seamless Scaling
      • Operational simplicity and transparency to applications.
      • Start small and add nodes as needed without disrupting ongoing applications.
      • Automatic sharding and scaling out as needs grow.
      • Scale up clusters for short-term needs and scale down afterward.

      • Operationally straightforward and performed without service disruption on the click of a button (APIs or terraform).
      • Ability to have asymmetric nodes in different regions to support scaling of your read replicas and regions in globally distributed multi-region clusters.

    How Scaling Works in YugabyteDB

    • Sharding
      • Data split into tablets (pieces of tables) placed on various nodes.
      • Deterministic mapping of rows to tablets ensures efficient data distribution.
      • YugabyteDB offers advanced sharding techniques that provide both automatic and customizable options to ensure optimal performance and scalability.
        • Range Sharding: allows data to be distributed in an ordered manner where each shard is responsible for a range of the key space. This is useful for scenarios where data access patterns need to perform range queries, such as leaderboard rankings.
        • Hash Sharding: distributes data based on a hash of the shard key, ensuring even distribution across all nodes. This is particularly beneficial for workloads with unpredictable access patterns, such as player transactions or session data.
    •  Rebalancing
      • Tablets are split and moved across nodes to maintain equal data distribution.
      • Data movement is automatic and without service interruption.
    • Adding Nodes
      • Automatic rebalancing of tablets to new nodes.
      • Increased capacity for handling larger workloads through parallel processing.

  4. Challenges with In-Game Features

    Features such as team lists and in-game messaging require gaming companies to manage a constantly evolving set of many-to-many relationships and messages. Efficiently handling queries related to team connections and providing real-time updates without degrading game performance is critical.

    YugabyteDB is a multi modal database and provides a YCQL Cassandra compatible API  and a YSQL PostgreSQL compatible API with ACID compliance, but none of the downsides of running Cassandra or PostgresQL at scale.

    A fully open source distributed database tailored for internet-scale, geo-distributed online gaming applications/platforms, YugabyteDB combines the best aspects of SQL and NoSQL databases, providing ACID transactions, relational modeling with joins, secondary indexes, unique constraints and schemas, plus NoSQL system benefits like scalability, resilience, flexible schema designs, JSONB and JSON documents.

    YugabyteDB’s capabilities naturally accommodate many-to-many relationships, essential for friends lists, in-App messaging and social network integrations. Developers have the flexibility to choose either YSQL, YCQL, or both options.

    For transactional and relational requirements where your app requires relational data modeling constructs like foreign keys and joins you can leverage YSQL. Games that demand low-latency, sub-millisecond queries for a seamless user experience, when automatic data expiration based on TTL (time-to-live) is crucial, or if you are leveraging stream processors like Apache SPARK or KSQL, YCQL might be a better fit.

Real World Examples:

  • In a fast-paced online multiplayer game where player stats and leaderboards need to be updated in real-time, YCQL can handle these requirements efficiently.
  • In betting games where quick responses can significantly enhance the user experience, but its equally critical to make sure the bets are consistent ensuring players get immediate feedback on their bets. This is achieved with YugabyteDB strong ACID compliance and low latency response based on the query optimizations delivered.
  • On a betting platform where user session data needs to expire after a certain period for security reasons; YCQL’s TTL-driven automatic data expiration can manage this seamlessly.
  • In games that require real-time data analysis and processing, such as updating odds in betting games based on live game data streams you can use Apache Spark or KSQL with YCQL integration.


The gaming industry demands a database solution that can keep up with the rapid evolution of technology and player expectations.
