Subject HBase relative write speed to HDFS
Date Mon, 04 Mar 2019 15:22:59 GMT
Hi,

I know no-one can give a precise figure. But I wondered what reasonable
write throughput (on a single Region Server writing into a single region,
ignoring compaction) folk would expect relative to HDFS, given you would
anticipate HBase becoming WAL-bound at it's max speed?

E.g. if you can achieve 200MB/s max throughput on HDFS what would you
broadly expect to achieve on HBase on the same node, given the write-path
includes both WAL and memstore updates?

Cheers, Owen
