(Nokia - IN/Bangalore) Sent: Friday, August 6, 2021 12:38 PM To: user@hbase.apache.org Subject: Hbase export is very slow - help needed Hi HBase team, We are trying to use Hbase export mentioned here: http://hbase.apache.org/book.html#export But it is happening sequentially row by row as seen from the logs. we tried many options of the Hbase export, but all were taking long time. Backup folder contents size: bash-4.2$ du -kh 16K ./tsdb-tree 16K ./tsdb-meta 60M ./tsdb-uid 5.9G ./tsdb 6.0G . took around 104 minutes for 6gb compressed data. Is there a way we can parallelise this and improve the export time. Below are the charts from Hbase . Export with single regionserver: [cid:image001.jpg@01D78ABF.E9E6C280] Export with two regionservers: [cid:image002.jpg@01D78ABF.E9E6C280] Scaling the HBase Region server also did not help, the export still happens sequentially. Thanks Jacob Mathews
