@richardstartin We did try the GC optimizations with -XX:+UseStringDeduplication but noticed elevated CPU usage affecting our query latencies. I want to clarify that we are not using Java's native `string.intern()` here but rather using manual interning. As I shared above, the implementation is based on article [here]( https://dzone.com/articles/duplicate-strings-how-to-get-rid-of-them-and-save). The Poc code is available here - https://github.com/vvivekiyer/pinot/commit/dc4538bd88f050c20f8dd17530d0e38052b92c65 . Do you see any potential issues mentioned in the article based on the code above? I'll also take a closer look at the article you shared. -- This is an automated message from the Apache Git Service.
