Hi , To improve client performance I changed hbase.client.scanner.caching from 1 to 50. After running client with new value( hbase.client.scanner.caching from = 50 ) it didn't improve execution time at all.
I have ~ 9 million small records. I have to do full scan , so it brings all 9 million records to client . My assumption -- this change have to bring significant improvement , but it is not. Additional Information. I scan table which has 100 regions 5 server 20 map 4 concurrent map Scan process takes 5.5 - 6 hours. As for me it is too much time? Am I write? and how can I improve it I changed the value in all hbase-site.xml files and restart hbase. Any suggestions.
