Tantor Labs (part of the Astra Group) has introduced the third generation of Tantor XData corporate database machines. According to the press service, Tantor XData Gen3 eliminates PostgreSQL limitations associated with a single server and provides full concurrent processing of transactional and analytical queries (HTAP). The solution is designed for large corporate customers who previously could not fully replace foreign DBMSs due to architectural limitations.
The new database machine is positioned as an alternative to Oracle Exadata, SAP HANA, and IBM Netezza and is aimed at information systems with critical requirements for scalability and business process continuity.
Tantor XData Gen3 implements a set of technologies, including horizontal scaling, shared storage with high IOPS, and the Tantor PFS distributed file system. The hardware is based on AMD Epyc processors.
The application accesses a single database, while the system itself balances the load and handles failures. The proprietary distributed file system Tantor PFS operates over a high-speed RDMA network (InfiniBand or RoCEv2) and the NVMe-oF protocol, providing all cluster nodes with a single block device with latencies comparable to using a local SSD.
During the press conference, Vadim Yatsenko, CEO of Tantor Labs, stated:
Until now, large companies could not completely migrate from Oracle, SAP, and IBM to PostgreSQL-based solutions, as they faced architectural limitations of this DBMS in practice: lack of horizontal scaling, degradation at 5,000 connections and above, and the inability to handle mixed workloads. With the release of the Tantor XData Gen3 database machine, these concerns are eliminated – for the first time, the Russian market receives a PostgreSQL-compatible database machine that provides horizontal scaling and stable operation with tens of thousands of connections, and allows the enterprise segment to replace foreign DBMSs while remaining in the proven Postgres ecosystem.
