The test data was stored in in-memory Array and Tuple tables, each
consuming about 80 GB. The population of the Tuple tables exceeded the
maximum memory thresholds (*).
As a fix,
- Reduce the Array cardinality from 200 to 150 and the number of rows
from 10 to 8 million, reducing memory consumption to ca. 50 GB. This
should pass the memory threshold and does not affect the test purpose.
- Don't test tuples. Due to their data layout, vector search is not
efficient anyways. Saves another 80 GB.
