I am trying to Fetch 50 TB of Hbase table using the GetHbase processor. Where I have 3 Node Nifi cluster(15 GB RAM) where i see I can Merge hbase record and put the record faster but as I cannot increase concurrent task in GetHbase processor this is fetching data slow I see that fetching the 400 GB data has taken 35 Hours. Where I have network bend-width is 1 GB/s. and data cardinality is low.
so how can I fetch the data faster to meet SLA ?
