Large dataset support #13

Closed mostlyAtNight closed 6 years ago

mostlyAtNight commented 11 years ago

Currently, Crayfish loads entire datasets into memory. Very large layers result in a bad allocation.

It would be better to load some of the dataset into memory and have functionality for loading the required output steps into memory automatically as required.

mostlyAtNight commented 11 years ago

As a quick workaround, the user could be given the option to load only some of the output steps rather than all

mostlyAtNight commented 11 years ago

For the 1.1 Milestone, we should ensure that a failed allocation does not tear-down QGIS. It should fail gracefully and also release any memory it consumed.

Done graceful fail and reporting in db95ff85c4a68b860404a38bdaa1732c70e57614

wonder-sk commented 11 years ago

Proper support for large data will be added after 1.1 release - removing this issue from 1.1 milestone.

Data loading is done in MDAL for QGIS 3.4 release
