For more information, see Creating UDXs in R. Db2 11.5.6 provides an R language option for the CREATE FUNCTION statement when building user-defined extensions (UDXs).
The latest compression techniques including page-based string compression will be applied.Įnhanced language support for the CREATE FUNCTION statement When enough data has been inserted in the efficient insert group format to reach an internal threshold, that existing data will automatically be converted into the standard column-based format. In contrast, bulk data insertion statements (SQL statements that insert a large number of new rows) will typically be inserted in the traditional fully-compressed column-based data page format. Data inserted via "trickle-feed" will typically be inserted uncompressed using the new efficient insert group data page format where multiple columns are grouped onto data pages for column-organized tables. In addition, the amount of storage required is reduced when column-organized tables are populated with a small number of rows using insert statements. This optimized trickle-feed insert processing is better able to apply page-based string compression which could result in better compression results than in prior releases. Inserts for data into column-organized tables via a "trickle-feed" (SQL statements that insert a small number of new rows) have improved processing time and reduced memory, storage, and log space consumption.
