Hi, I ran into the fact that I can not achieve high insertion speed and I start to experiment with https://github.com/cloudera/kudu-examples/tree/ master/java/insert-loadgen. My slightly modified code (recreation of table on startup + duration measuring): https://gist.github.com/xkrt/9405a2eeb98a56288b7c5a7d817097b4. On every run I change kudu-client version, results:
kudu-client-ver perf 0.10 Duration: 626 ms, 79872/sec 1.0.0 Duration: 622 ms, 80385 inserts/sec 1.0.1 Duration: 630 ms, 79365 inserts/sec 1.1.0 Duration: 11703 ms, 4272 inserts/sec 1.3.1 Duration: 12317 ms, 4059 inserts/sec As can you see there was a great degradation between 1.0.1 and 1.1.0 (about a ~20 times!). What could be a problem, how can I fix it? (actually I interested in kudu-spark, so probably using of kudu-client 1.0.1 is not right solution?). My test cluster: 3 hosts with master and tserver on each (3 masters and 3 tservers overall). No extra settings, flags used: fs_wal_dir fs_data_dirs master_addresses tserver_master_addrs -- with best regards, Pavel Martynov
