Phases of a load operation

-
A complete load operation consists of five distinct phases; they are as follows: Analyze phase Load phase Build phase Delete phase Index copy phase Analyze phase:  This phase of the Load process is only utilized when a column-organized table is being loaded and the column compression dictionaries need to be built. This happens during a LOAD REPLACE operation, a LOAD REPLACE RESETDICTIONARY operation, a LOAD REPLACE RESETDICTIONARYONLY operation, or a LOAD INSERT operation (if the column-organized table is empty). For column-organized tables, this phase is followed by the load, build, and delete phases. The following diagram showcases the steps involved in the analyze phase. The analyze phase is invoked if you are loading data for the first time into a column-organized BLU acceleration table using LOAD INSERT, or running a LOAD REPLACE with RESETDICTIONARY or RESETDICTIONARYONLY clause. Load phase:  During this phase, data is loaded into the table, and index keys and table stat...
