What is the problem that Object Store solves ? Modern enterprise systems increasingly deal with massive volumes of unstructured data such as documents, logs, media files, and backups. Traditional relational databases are not optimized for such workloads. What is Object Store ? Object storage—commonly referred to as blob storage—addresses this gap by providing scalable, durable, and cost-efficient storage for unstructured data. Object storage is a storage architecture designed to manage unstructured data as discrete units called objects.  Each object consists of: Binary data (file content) : Image , File etc Metadata (descriptive attributes) : File size, Content type, Last modified timestamp, Storage class (hot, cool, archive) Unique identifier (key or URL) : unique path-like string used to locate a blob inside a bucket Unlike file systems or relational databases, object storage does not rely on hierarchical file structures or schemas. The SAP BTP Object Store service is a managed, ...

In SAP Business Technology Platform (BTP), organizing your resources effectively is crucial for efficient management and scalability. This blog provides a comprehensive overview of global accounts, directories, subaccounts, and entitlements within SAP BTP. What is a Global Account in SAP BTP? A global account in SAP BTP represents the contractual agreement you have with SAP. It serves as the top-level container for managing various resources, including directories, subaccounts, members, entitlements, and quotas. Within a global account, you receive entitlements and quotas for platform resources, which can be allocated to subaccounts for actual consumption. How Do Directories Function in SAP BTP? Directories in SAP BTP allow you to organize and manage your subaccounts based on your technical and business requirements. A directory can contain other directories and subaccounts, enabling you to create a hierarchical structure. This hierarchy can be up to 7 levels deep, with the global ac...

Introduction: In the dynamic landscape of database administration, ensuring the robustness of a system is paramount. One crucial aspect that demands meticulous attention is the recovery process following a system failure. Two key performance indicators (KPIs) stand out in this realm – Recovery Point Objective (RPO) and Recovery Time Objective (RTO) . In this technical blog, we will delve into the significance of these KPIs for HANA database administrators and explore strategies to optimize them. Recovery Point Objective (RPO): RPO is a critical metric that defines the maximum acceptable data loss in the event of a system failure . For HANA database administrators, establishing an RPO involves a careful balance between data consistency and the overhead of continuous data replication. Continuous Data Backups: To meet stringent RPO requirements, implementing continuous data backups is imperative. Utilizing HANA's native backup capabilities and integrating them with a robust backup s...

The SAP HANAsitter is configured to perform default checks once every hour to ascertain the online and primary status of SAP HANA. Upon confirmation, it initiates tracking procedures, which involve regular responsiveness assessments (typically every minute). If SAP HANA becomes unresponsive, the HANAsitter commences recording activities, potentially capturing call stacks of active threads, run-time dumps, index server gstacks, and/or kernel profiler traces, although, by default, no recording occurs. When SAP HANA is responsive, the script scrutinizes critical features, including a standard check for more than 30 active threads. If this threshold is exceeded, the script triggers recording. Upon completing the recording process, the script exits, with an option to be configured for restart using the command line. Setup Steps Overview: Begin by creating an SAP HANA user with the desired name (e.g., HANASITTER) and assign the CATALOG READ privilege to it. Establish a user key in the hdbuse...

What is MVCC? MVCC is a database concurrency control method that allows multiple transactions to occur concurrently without conflicting with each other. In a nutshell, it ensures that each transaction sees a snapshot of the database at a specific point in time, even if other transactions are making changes concurrently. MVCC in SAP HANA: SAP HANA uses MVCC to manage concurrent access to data. Each transaction in HANA sees a consistent snapshot of the data at the time the transaction began. This is achieved by maintaining multiple versions of a data row, each associated with a specific transaction or point in time. The Issue of Huge MVCC Versions: Now, the term "Huge MVCC Versions" indicates a situation where there is a significant number of these versions for a particular set of data. Here's why this might become a problem: Increased Memory Usage: Each version of a data row consumes memory. As the number of versions increases, the overall memory consumption by the databas...
