In their own words
IBM Db2
IBM Db2 is a database for low-latency transactions, real-time analytics, and mission-critical workloads. It supports transactional, analytical, and operational work on the same database and can feed Db2 Warehouse and watsonx.data. AI-powered query optimization uses historical query patterns to adjust execution plans and automate tuning. Db2 12.1.2.0 adds a VECTOR type and SQL vector-distance queries for semantic search, retrieval-augmented generation, and recommendation systems. Db2 pureScale supports continuous availability on premises or in the cloud, with Pacemaker integration. Security features include access controls, encryption in transit and at rest, behavior monitoring, and data masking. IBM documents integrations with DataStage, Segment, Cognos Analytics, Looker, Tableau, Excel, SPSS Statistics, SAS, and R. Supported deployments include self-hosting and Amazon RDS for Db2. Free plans are available; Performance is listed at $630 a month, billed hourly.
YDB
YDB is an open-source distributed SQL database for OLTP, OLAP and streaming workloads. It provides global ACID transactions, strong consistency, automatic sharding and rebalancing, and independent scaling for compute and storage. Columnar tables and a distributed vectorized query engine support analytics. YDB Topics supports Kafka API 3.4.0, exactly-once delivery and automatic partitioning. A native vector index handles approximate nearest-neighbor queries for semantic search, recommendations and retrieval-augmented generation pipelines. Deployments can run on premises, on virtual machines with Ansible, or in cloud environments with Kubernetes. Security includes internal and directory-based external users, plus user and group rights. Integrations listed include DBeaver, DataGrip, Grafana, Airflow, Spark, Kafka API, dbt, SQLAlchemy and LangChain. Open-Source costs nothing under Apache 2.0. Managed Serverless is also free, usage-billed with monthly free allowances.
