[jboss-jira] [JBoss JIRA] (WFCORE-2780) Improve buffer-pool model description

Improve buffer-pool model description ------------------------------------- Key: WFCORE-2780 URL: https://issues.jboss.org/browse/WFCORE-2780 Project: WildFly Core Issue Type: Bug Reporter: Romain Pelisse Assignee: Romain Pelisse Priority: Minor Current state of buffer-pool model description: {code} [standalone@localhost:9990 /] /subsystem=io/buffer-pool=foo:read-resource-description { "outcome" => "success", "result" => { "description" => "Defines buffer pool", "capabilities" => [{ "name" => "org.wildfly.io.buffer-pool", "dynamic" => true }], "attributes" => { "buffer-size" => { "type" => INT, "description" => "The size of each buffer slice in bytes, if not set optimal value is calculated based on available RAM resources in your system.", "expressions-allowed" => true, "required" => false, "nillable" => true, "access-type" => "read-write", "storage" => "configuration", "restart-required" => "all-services" }, "buffers-per-slice" => { "type" => INT, "description" => "How many buffers per slice, if not set optimal value is calculated based on available RAM resources in your system.", "expressions-allowed" => true, "required" => false, "nillable" => true, "access-type" => "read-write", "storage" => "configuration", "restart-required" => "all-services" }, "direct-buffers" => { "type" => BOOLEAN, "description" => "Does the buffer pool use direct buffers, some platforms don't support direct buffers", "expressions-allowed" => true, "required" => false, "nillable" => true, "access-type" => "read-write", "storage" => "configuration", "restart-required" => "all-services" } }, "operations" => undefined, "notifications" => undefined, "children" => {} } } {code} Following improvements should be done to it: * In {{buffer-size}} and {{buffers-per-slice}} description there is mentioned something called 'slice'. Nowhere is described what it is. Suggested improvement: Explain what slice is, preferably in buffer-pool model description. * In {{buffer-size}} and {{buffers-per-slice}} description there is this sentence: ''...if not set optimal value is calculated based on available RAM resources in your system" - how it is calculated? Is there any default fixed value? User would like to know this. Suggestion: Add explanation about default value. * In {{direct-buffers}} description there is mentioned that some platforms don't support direct buffers? Is there mentioned which one or what determines whether direct buffers are supported on given platform? Suggested improvement: Explain what element determines whether direct buffers are supported.
