1 put to 2-5 reads for the "hdfs files" (estimated) and 1 put to hundreds of reads in the hbase table So in short form: = for the files * number of puts ~ gets * "small" number of puts and gets * "small" number of files * "large" amount of disk space = for the rows * number of puts << gets * "large" number of gets (and puts) * "large" number of rows (and rows*columns) * "small" amount of disk space Small and large are in '"' because large and small are only understood in comparison to the other task. So, basically, this are two completely different tasks. This is the origin of my question. > Have you looked at HBASE-10070 'HBase read high-availability using > timeline-consistent region replicas' (phase 1 has been merged for the > upcoming 1.0 release) ? No. But I look now ;). Best wishes and thanks for the reply Wilm
