Hello! In the context of a WIP Calcite upgrade [1] I ran into shading issues in druid-handler (an ASM failure when relocating Calcite's SqlFunctions.class, tracked upstream in CALCITE-6393). I worked around it by dropping the Calcite relocation in druid-handler/pom.xml, but it prompted me to re-open an earlier discussion [2] about whether we should still be carrying this module at all.
Nothing seems to have changed since it was last raised: we're still on Druid 0.17.1 [3] (released in 2020), which has a number of unpatched CVEs [4], and there's been essentially no meaningful development in the module [5]. So the same questions remain open: - Are there any active users of druid-handler? - If there are users but no maintainers, should we deprecate the module (docs + build) and target removal in a future major release? - If there are neither, shall we drop it now?
