- Comparison between the different types of copy for the HFSQL context:
| | | | Type of copy | Benefits | Drawbacks |
|---|
| Full copy | Copies: - the extensive connection parameters (connections, physical paths, ...).
- the positions, the filters, ... defined on the data files.
- the queries.
| Memory consumption (on the client and on the server). | | Light copy | Copies the extensive connection parameters (connections, physical paths, ...). No memory consumption on the server. | The records and the current filters are not copied. Therefore, the records must be repositioned by HReadSeek for example. No copy of queries. Memory consumption on the Client computer | | Delayed copy | No memory consumption (on the client and on the server). | Risk: If the extended connection parameters are modified, the last modification will be taken into account. The records and the current filters are not copied. Therefore, the records must be repositioned by HReadSeek for example. No copy of queries. |
In most cases, the delayed copy is recommended provided that you don't change the connection parameters and that you perform the necessary calls to HReadSeek.
