| ### IOQ classes |
| The following are the list of IOQ classes: |
| |
| * interactive |
| * db_update |
| * view_update |
| * db_compact |
| * view_compact |
| * internal_repl |
| * low |
| |
| |
| ### Bypassing IOQ |
| One can configure an ioq bypass, which removes an IO class from prioritization, |
| as below: |
| |
| config:set("ioq.bypass", "view_update", "true") |
| |
| Note that setting an IOQ bypass can effectively trump all other classes, |
| especially in the case of an interactive bypass v. compaction. This can lead |
| to high disk usage. |
| |
| ### Setting priorities |
| The priority for a class can also be set ala: |
| |
| config:set("ioq", "compaction", "0.3") |
| |
| Or globally, using snippet/rpc: |
| |
| s:set_config("ioq", "compaction", "0.314", global) |
| rpc:multicall(config, set, ["ioq", "compaction", "0.217"]) |
| |
| As the interactive class is 'everything else' its priority cannot be directly |
| set. |
