The training materials have been updated from version 8a 9.5.2 to the latest version 9.5.3, with updates in chapters on principles, installation, and management. The GBASE official website offers the 8a v9.5.3 free version installation package for download. To help new and existing students understand what updates have been made to the 8a certification training content, we will explain from three aspects: 9.5.3 version product features, installation package changes, and training content updates.

GBase 8a MPP Cluster V9.5.3 New Version Introduction
In 2021, Nanda General officially released GBase 8a MPP Cluster V9.5.3. After more than two years of continuous updates and iterations, its functions have become increasingly complete, achieving over 100 functional requirements, and it has become the main version promoted by GBase 8a MPP Cluster in the market.
Compared with V9.5.2, V9.5.3 mainly has the following improvements and enhancements:
1. Enhanced stability: GCware is decoupled and separated from GCluster. The three functional clusters—GCluster scheduling cluster, Data computing cluster, and GCware management cluster—can be deployed independently with clearer responsibilities. Supports node status monitoring mechanism to improve cluster stability, and enhances stability during node replacement;
2. Performance improvement: Supports multi-instance deployment to improve overall cluster performance, especially in NUMA architecture server environments; improves small file loading performance, union query performance, and performance in dblink high network latency scenarios.
3. Compatibility improvement: Enhanced function and syntax compatibility with heterogeneous databases such as Oracle, GreenPlum, Teradata; supports loading of orc and json format data;
4. Security improvement: Refined drop permission and unmask data masking permission management, transparent storage encryption supports national secret algorithms, supports Kafka security authentication.

GBase 8a MPP Cluster Certification Training Content Upgraded to V9.5.3
In 2021, the Nanda General Training Center launched the 'GBase Academy' platform for online training. The GBase 8a MPP Cluster GDCA training materials were written based on the then-main version V9.5.2, and the accompanying 8a installation package version was also V9.5.2 . A license was required when installing the 8a database.
In 2024, version 9.5.3 has become the main version promoted by GBase 8a MPP Cluster in the market. Compared with V9.5.2, the architecture of the virtual cluster has changed, with gcware separated. The gcware cluster and GCluster cluster nodes can be deployed separately, resulting in changes in installation, service start/stop, management tool display, etc. SQL syntax usage is basically the same. The 8a GDCA training materials follow the product upgrade, only synchronously updating content on core technology, installation, and management. The original SQL training content remains unchanged. The main changes are as follows:

The training materials have been upgraded from 952 to 953, with 40% of the training content updated. Correspondingly, the certification exam questions have also been updated by 40%. The 2024 8a certification training will be conducted using the new training materials. Students who have previously participated in training and obtained the GBase 8a Management Engineer certificate can learn about the new features of 953. The upgrade from 952 to 953 is within the same major version V9, only a minor version change, which will not be reflected on the certification certificate, so there is no need to retrain or retake the exam.
On March 6, 2024, the first certification training after the GBase 8a upgrade to 953 will be held. The course outline is as follows:
