Costs of Partitioning

Costs of Partitioning




Depending on the actual value distribution and partitioning criteria, the main memory consumption of a table might increase or decrease when it is changed from a non-partitioned to a partitioned table. While this does not initially appear very intuitive, the root cause for this lies in the dictionary compression that is applied.

  • Increased memory consumption due to partitioning

    A table has two attributes, MONTH and YEAR, and contains data for all 12 months and two distinct years (2013 and 2014). When the table is partitioned by YEAR, the dictionary for the MONTH attribute needs to be held in memory twice (both for 2013 and 2014), therefore increasing memory consumption.
  • Decreased memory consumption due to partitioning

    A table has two attributes, GENDER and FIRSTNAME, and stores data about German customers. When the table is partitioned by GENDER, it is divided into two groups (female and male). In Germany, there is a limited set of first names for both females and males. As a result, the FIRSTNAME dictionaries are implicitly partitioned as well into two almost distinct groups, both containing almost n/2 distinct values, compared to the unpartitioned table with n distinct values. Therefore, to represent those values in the index vector, only n-1 bits are required instead of n bits in the original table. As there is virtually no redundancy in the dictionaries, memory consumption can be reduced by partitioning.

SAP HANA Query Execution Engine

SAP HANA Query Execution Engine






1. HEX engine

The SAP HANA Execution Engine (HEX) is a new engine that combines the functionality of other engines, such as the join engine and OLAP engine. Queries that are not supported by HEX or where an execution is not considered beneficial are automatically routed to the former engine.


2. ESX engine

The SAP HANA Extended SQL Executor (ESX) is a new frontend execution engine that replaces the row engine in part, but not completely. It retrieves database requests at session level and delegates them to lower-level engines like the join engine and calculation engine.





3. Join engine

The join engine is used to run plain SQL. Column tables are processed in the join engine.


4. OLAP engine

The OLAP engine is primarily used to process aggregate operations. Calculated measures (unlike calculated columns) are processed in the OLAP engine.


5. Calculation engine

Calculation views, including star joins, are processed by the calculation engine. To do so, the calculation engine may call any of the other engines directly or indirectly.


6. Row engine

The row engine is designed for OLTP scenarios. Some functionality, such as particular date conversions or window functions, are only supported in the row engine. The row engine is also used when plain SQL and calculation engine functions are mixed in a calculation view.


7. MDS engine

SAP HANA multi-dimensional services (MDS) is used to process multidimensional queries including aggregation, transformation, and calculation.
The queries are translated into an SAP HANA calculation engine execution plan or SQL, which is executed by the SAP HANA core engines.
MDS is integrated with the SAP HANA Enterprise Performance Management (EPM) platform and is used by reporting and planning applications.
The query languages currently supported use the Information Access (InA) model. The InA model simplifies the definition of queries with rich or even complex semantics. Data can be read from all kinds of SAP HANA views, EPM plan data containers, and so on. The InA model also includes spatial (GIS) and search features.

SQL Processing



SQL Processing

The SAP HANA SQL process starts with a SELECT statement, which is then looked up in the cache, parsed, checked, optimized, and made into a final execution plan. An overview is shown below:
The main components involved in processing an SQL query are the session, the SQL frontend, the SQL optimizer, and the execution plan.
