Esteban Gutierrez created HBASE-17756:
-----------------------------------------
Summary: We should have better introspection of HFiles
Key: HBASE-17756
URL: https://issues.apache.org/jira/browse/HBASE-17756
Project: HBase
Issue Type: Brainstorming
Components: HFile
Reporter: Esteban Gutierrez
[[email protected]] was suggesting to use DataSketches
(https://datasketches.github.io) in order to write additional statistics to the
HFiles. This could be used to improve our split decisions, troubleshooting or
potentially do other interesting analysis without having to perform full table
scans. The statistics could be stored as part of the HFile but we could
initially improve the visibility of the data by adding some statistics to
HFilePrettyPrinter.
