Subject [GitHub] orc issue #60: ORC-101 fix broken encoding for string and decimal bloom filt...
Date Tue, 20 Sep 2016 19:05:00 GMT
Github user omalley commented on the issue:

    Ok, the latest push has a few changes:
    * bloom_filter_utf8 streams use a new encoding with bytes instead of long[]. This is much
more efficient for performance and storage size.
    * all column types now have bloom_filter_utf8 streams (largely to get the new representation)
    * the default is to just write the new bloom_filter_utf8 streams that old readers will
ignore. There is an option to write both bloom_filter and bloom_filter_utf8 streams to support
old readers.
    * there is an option for new readers to ignore the old bloom filters.
    * files generated after hive-12055 will correctly use the utf8 encoding even for the bloom_filter
