In their own words
GridGain
GridGain Platform is an in-memory computing system for transactional, streaming, and analytical workloads. It keeps data in memory, on disk, or both through configurable disk persistence, and supports ANSI SQL, key-value APIs, and ACID transactions. Workloads run across horizontally scalable clusters deployed on premises or in public or private clouds; GridGain says its architecture can scale to petabytes of in-memory data. Listed capabilities include transaction processing, advanced analytics, AI/ML operations, data hub, system of record, stream processing, and vector search. Supported data models include key-value, relational, document, geospatial, and unstructured data. Integrations include Kafka, Oracle Golden Gate, Data Lake Accelerator, Spring, Spark, Hibernate L2 Cache, MyBatis L2 Cache, and Cassandra. GridGain 9 supports SSL/TLS, while Enterprise and Ultimate add role-based authorization and transparent data encryption. Pricing is on request, with a 30-day trial and no free plan.
VoltDB
VoltDB is a distributed, in-memory database and real-time decisioning layer for data processing, stream ingestion, business logic, and AI integration. Its database partitions data and stored procedures so queries can run in parallel while maintaining ACID consistency. Volt Active Data says Volt is built to move from ingest to action in under 10 milliseconds. Clusters scale by adding nodes, with partitioning automated from the schema. Volt connects directly to Kafka or CDC streams and can expose decisions through SQL, REST, or Kafka topics. It supports on-premises, cloud Kubernetes or VM-based, and hybrid deployments. Production databases support Debian 12.11 or later, RHEL 8.8 or later, Rocky Linux 8.8 or later, and Ubuntu 20.04, 22.04, or 24.04; macOS 13 or later is supported for development. Enterprise Edition provides command logging, locally replicated partitions, and wide-area database replication. Authentication, role-based authorization, and TLS/SSL or Kerberos communications are available, but security is disabled by default. The free Developer Edition is not intended for production workloads. A free 30-day trial is listed for Confluent users; production pricing is on request.
