### What changes were proposed in this pull request? Implement support for tuple sketches in Apache Spark to enable approximate set cardinality, frequency, and similarity computations over multiple dimensions efficiently ### Why are the changes needed? Spark currently lacks support for tuple sketches, which allow efficient approximate computations over key–value data. These changes add tuple sketch support to enable fast and memory-efficient estimates of distinct counts, frequencies, and set similarities across multiple dimensions. ### Does this PR introduce _any_ user-facing change? Yes ### How was this patch tested? WIP ### Was this patch authored or co-authored using generative AI tooling? Yes -- This is an automated message from the Apache Git Service.
