Hi
I am trying to add a large number of records to a file (more than 1 million records to a file with millions of records) with several keys. Mostly composite keys none unique. Is there a way to prevent reindexing after every record is added? I am checking for existence of primary key and using HAdd if record is not found and HModify to update. Is there a better way to do this? |

If you create a hyper file from Analysis with keys
defined and the file will be created automatically
after generation and running from RAD. All index keys
are well-built.
When applying HAdd, HModify, HDelete, all keys are
automatically updated, no re-indexing process is needed.
It's quite unlikely to get Hyper file crashed because of
its stabilities or just apply HReindex() if it does.
