Recently See Git lfs article, read the next introduction, is really good, similar to Git, but a little different oh. If you want to track the files, go ahead. git lfs track *.pdf In the past, when we were in Tableau's big files, we were going to use git, but it would be slow, and maybe Git server would be hung up. Git in version code, will be differ, just make changes to the change record, do not know git lfs binary is how to do, perhaps each file saved a portion, this is simple (and git trea

-threaded algorithm, but Kylin uses a parallel algorithm.User-TOPN queries, such as fetching 100 data, are written as SQL statements as shown in. and Kylin will automatically adapt to such a SQL to directly use the pre-aggregated good results, so at run time Kylin just put the pre-calculated 1000, 10,000 item directly back to the good, there is almost no online calculation, the speed will be very fast.　　7. Integration of analysis tools　　In the new version, Kylin also added some ODBC interfaces,
