How much extra working memory will be required for DB operations and temporary computations? The number of indexes (SAP HANA requires fewer indexes), and more.ģ. Such as the nature of the data, its organization and data-types, the presence of repeated values, The achieved compression ratio depends on many factors,
To best compress each table column separately. The SAP HANA Column Store automatically uses a combination of various advanced compression algorithms (dictionary, LRE, sparse, and more) What is the expected compression ratio that SAP HANA will apply to these tables? This estimate may only be partially meaningful.Ģ. You may be able to estimate this based on the size of your existing data,īut unless you precisely know the compression ratio of the existing data and the anticipated growth factor, What is the size of the data tables that will be stored in SAP HANA? To understand memory sizing, you will need to answer the following questions:ġ. Memory sizing is the process of estimating, in advance, the amount of memory that will be required to run a certain workload on SAP HANA. In such distributed scenarios, this discussion of memory usage applies to each of the hosts of an SAP HANA system, separately. It is possible to partition large tables, and even distribute these partitions over multiple hosts.

Since the code and program stack size are about 6 GB, almost all of the Used Memory is in fact used for storing tables, computations and database management.
The SAP HANA Used Memory, consisting of code, stack and data, is shown below: This is the most precise indicator of the amount of memory that SAP HANA uses. SAP refers to the total amount of memory actually in use as the SAP HANA Used Memory. Structures required for managing a database.Īt any given point, only parts of the memory pool are really in use. The memory pool is used to store all the in-memory data and system tables, thread stacks, temporary computations and all the other data SAP HANA has become the fastest growing product in SAP’s history.Īs an in-memory database, it is particularly critical for SAP HANA to carefully manage and track its consumption of memory.įor this purpose, SAP HANA manages its own data memory pool by requesting memory from the OS, possibly in advance of using it. Thousands of deployments are in progress.
The key performance indicators of SAP HANA appeal to many of our customers, and By keeping all relevant data in main memory (RAM),ĭata processing operations are significantly accelerated. Provided by modern hardware to increase application performance.
