【问题描述】:
默认吞吐量如下(cassandra.yaml):
compaction_throughput_mb_per_sec: 16
stream_throughput_outbound_megabits_per_sec: 200
inter_dc_stream_throughput_outbound_megabits_per_sec: 200
为了加快压缩之类的速度,我设置了这些值:
$ nodetool getcompactionthroughput
Current compaction throughput: 10000 MB/s
$ nodetool getstreamthroughput
Current stream throughput: 10000 Mb/s
$ nodetool getinterdcstreamthroughput
Current inter-datacenter stream throughput: 10000 Mb/s
Cassandra 数据目录由 SSD 和 HDD 支持,具体取决于密钥空间。
应用如此高的值是否有任何影响(如读取或写入超时)?
谢谢
