v0.28.0

!!! IMPORTANT !!!

This release contains database schema additions, so that the database can't be opened with older versions of Blaze. Downgrades are not possible.

Notes

A new index called PatientLastChange which will be automatically created and filled at the startup of Blaze. The index is used for the new CQL cache feature (#1051). Except for the caching, Blaze will work fully during index buildup. The index will be ready once the log message "Finished building PatientLastChange index of main node." appears.

After the index buildup, the CQL Cache can be activated by setting CQL_EXPR_CACHE_SIZE to a size of heap memory in MiB and restarting Blaze. A default of 128 MiB is recommended for instances with up to 100 k Patients and 1024 MiB for instances with 1 million patients.
