druid.segmentCache.locations multiple locations SSD (druid 9)


We are trying to use historical node with druid.segmentCache.locations with multiple locations, one of which happens to be SSD. We’d obviously like the SSD to fill up first and then the other locations.

What we see is that no matter the order, the none SSD location is used and the other location ignored.

What’s the priority alg for using multiple storage locations?


The one with the most available space gets used first.
