ALTIBASE vs Apache Geode

ALTIBASE is a relational database engine that combines in-memory and on-disk storage. It can run entirely in memory, entirely on disk, or in a hybrid mode, with features for both OLTP and OLAP workloads. Built-in replication supports synchronous or asynchronous consistency and Active-Active or Active-Standby architectures. Listed interfaces include ODBC, JDBC, .NET and Entity Framework, OLEDB, Embedded SQL, CLI, Perl DBD, and PHP. ALTIBASE V7.3 lists migration support for Oracle, PostgreSQL, MySQL, SQL Server, Tibero, and CUBRID, along with DBeaver compatibility through plugins. Its listed utilities cover querying, replication management, profiling, monitoring, migration, exporting, and loading data. Security capabilities include SSL/TLS communication, SQL auditing, password policies, IP access control, object privileges, and methods to integrate third-party encryption. The Linux, self-hosted product offers a free A+ Edition for development, testing, and education; it is not for commercial use and is limited to 128 concurrent users, 10 GB in-memory, and 50 GB disk database. Enterprise subscription pricing is available on request.

Apache Geode is a data management platform for applications that need consistent, real-time access to data across distributed cloud architectures. It combines replication, partitioning, and distributed processing for low-latency, high-concurrency workloads. Data is stored in memory, with options for off-heap storage, compression, disk overflow, eviction, and expiration. Its write-ahead-log persistence is designed to speed parallel recovery of nodes or a whole cluster. Geode supports distributed ACID transactions and OQL queries, including joins. Clients can subscribe to server-side data events; servers can respond synchronously or asynchronously with ordered delivery. Clusters can replicate across WANs in several arrangements, including active-active, active-passive, ring, hub-spoke, and star. Listed client options include Java, C++, and C# .NET Framework, alongside a REST API for other languages. The software is free as binary and source distributions under the Apache License. Authentication, authorization, role-based access control, and SSL are available, but are not active in the default installation.
