Use link/unlink for hidden nodes link/unlink is supported by JInterface which presents as a hidden node, this enhancement to ioq allows us to ditch scalang among other effects.
The following are the list of IOQ classes:
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.
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.
