Data Processing Engines

  • Legacy and LegacyOptimized Calculation Engines

    Legacy is the originally developed data engine. Demonstrates acceptable performance if a data-source contains less than 100,000 rows. The engine is not optimized for summary and aggregate calculations. Best suited for a dozen of fields in the row area that contains mostly unique values.

    The LegacyOptimized engine is available from v17.1. The engine supports the Legacy engine’s features, inherited from legacy API, and increases data processing speed (up to 30 times faster). From v17.2, the Pivot Grid’s LegacyOptimized mode can utilize multi-core processors for data operations. The control splits bound records into bulks and processes them in parallel threads. Data processing speed increases proportional to the number of CPU cores. Allows you to restore a layout configured in Legacy mode. From v18.2, LegacyOptimized is a default engine.

  • Optimized Calculation Engine

    The newest data engine. Available from v19.2. This engine uses Data Binding API that provides more flexible way to define data processing logic and performs Intermediate Level Aggregations and Calculations. Doesn’t support a layout configured in the Legacy and LegacyOptimized modes.
