notbdu opened a new issue #6341: Questions: Joining Columns/Compression/Segments URL: https://github.com/apache/incubator-druid/issues/6341 Hi, I had a few questions: - Where is the code located that reads segment files for separate columns and joins them together? - Where is the code that writes/reads segment files to/from disk? - For float/int compression strategies: - Does druid sort the floats/int before compressing? - If sorting happens before storing on disk, how are the row ids determined from the sorted values. - Does druid support variable length columns? - If variable length columns are supported, how are the row ids determined from the variable length data?
