Amazon DynamoDB vs FairCom DB

Amazon DynamoDB is a serverless, managed NoSQL database for applications that need single-digit millisecond performance at any scale, according to AWS. Users do not provision or patch database servers, and tables can scale automatically, including to zero in on-demand mode. Primary keys and global or local secondary indexes provide ways to query data. Global tables support multi-Region, multi-active operation; AWS says they are designed for up to 99.999% availability. The database also supports native vector search for similarity searches and agent memory use cases. Data is encrypted in transit and at rest by default, and IAM policies can restrict access to specific items and attributes. Point-in-time recovery provides continuous, per-second backups and restoration within a configured period of 1 to 35 days. A free tier is listed with 25 WCUs, 25 RCUs, and 25 GB of storage per Region and payer account, among other limits. On-demand capacity is billed per request consumed; provisioned capacity is billed for specified capacity even if usage is lower.

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.
