Performance Mode
The io_perf_mode
storage setting tunes the parallelism and striping behavior when reading data from that particular storage. It has one of three settings:
Keyword | Integer Value |
---|---|
aggressive | 0 |
moderate | 1 |
relaxed | 2 |
If the io_perf_mode
value is a keyword (not an integer), the field will be updated to its integer value.
The default is aggressive
, which performs more read requests from storage with a smaller byte range. If you're experiencing throttling from cloud vendors who have stringent limits on iops, set it to moderate
or even relaxed
, which performs fewer, but larger requests. The example below sets it to moderate
.
"storage" : {
"name": "hdx_primary",
"description": "The initial bucket that comes up with the hdx cluster",
"org": "<example org>"
"settings": {
"bucket_name": "<example name>",
"bucket_path": "/",
"region": "<example region>",
"cloud": "<vendor",
"endpoint": "<endpoint URL>",
"io_perf_mode": "moderate"
}
}
