Apache Ignite vs FairCom DB

Apache Ignite is a free, open-source, memory-first distributed SQL database for high-velocity workloads. It keeps data primarily in memory, with persistence available through AIPERSIST, and supports ACID transactions across partitions using Raft consensus. MVCC snapshot isolation enables non-blocking reads. SQL access includes JDBC drivers, a Table API and native APIs, while catalog-driven schema management allows column and index changes without stopping the cluster. DataStreamer handles high-throughput writes with backpressure control. Native clients are listed for Java, .NET, C++ and Python, alongside AWS, Azure, GCE and Spring extensions. Built-in operational capabilities include authentication, SSL/TLS security, OpenTelemetry metrics, recovery snapshots and backups. Listed uses include event stream processing, microservices state management, session management and AI/ML feature stores. Ignite is self-hosted and available through binary, source, Docker and Maven/Gradle options. The project identifies Ignite 2 as a long-term-support release recommended for existing deployments.

FairCom DB is a multimodel database for developing on-premises applications, combining JSON, key-value, SQL, and ISAM or record-buffer capabilities in one server. Applications can use different models over the same data, query with JSON or standard SQL, and receive query results as JSON. SQL connections are available through JDBC and ODBC, while the built-in API Explorer can help create JSON actions. The database can operate as a traditional server or be embedded in an application. Replication options address high availability and disaster recovery, with ACID compliance or eventual consistency. DB Notify publishes data-change events as JSON messages and integrates with MQTT, AMQP, and Kafka. FairCom DB v13 uses OpenSSL v3 for secure communications and supports X.509 client certificate authentication. File and user security are available only in the client/server operational model. A free Developer’s Edition is limited to development environments and has a three-hour timeout; production licensing requires contacting sales. A free trial is also available, and pricing is on request.
