Data Fits Into Memory

The term "fit into memory" as used in the context of Incremental Data Retrieval deserves some elaboration:

When data is first read (catalog is opened / refreshed / new search performed), the number of objects read is limited by the Initial Load setting. At this point "fits into memory" means "is less or equal than Initial Load".

This, however, does not mean that more data cannot be read to memory. As a matter of fact, more data most likely will be read (in increments of size specified by the Load Increment setting) so it is possible that after several incremental reads all data contained in a catalog really is in memory. Because the maximum amount of data built up by incremental reading is limited by the Maximum Load setting, at this point the term "fits into memory" means "is less or equal than Maximum Load".

As a result, an operation which was not available initially when the catalog was opened may become available in the course of working with the catalog. Refer to the example in the Limitations chapter.
