Dear Kudu Developers, I am a new tester for kudu, our kudu cluster has 3+12 nodes, 3 seperated master node and 12 tablet node, each node has 128GB memory, and 1 SSD for WAL, 6 1TB SAS for data
we are using CDH 5.7.0 with impala-kudu 2.7.0 and kudu 0.9.1 parcels, we set 16GB memory hard limit for each tablet node. one of our test table is about 80-100 columns and 1 key column, with java client, we can insert/upsert into the kudu table about 100,000/s the kudu table has 300m rows, and about 300,000 rows update per day, we also use java client upsert API to update the rows we found the kudu cluster maybe encounter abnormal high disk I/O rate, about 1.5-2.0Gb/s, even we just update 1,000~10,000 rows/s i would like to know, with our row update frequency, is the cluster high disk rate normal or not? Thanks. Best Regards [email protected]
