Examples with IgniteComponent org.apache.ignite.internal.manager.IgniteComponent used on opensource projects

Example 1 with IgniteComponent

use of org.apache.ignite.internal.manager.IgniteComponent in project ignite-3 by apache.

the class IgniteImpl method start.

/**
 * Starts ignite node.
 *
 * @param cfg Optional node configuration based on {@link org.apache.ignite.configuration.schemas.runner.NodeConfigurationSchema} and
 *            {@link org.apache.ignite.configuration.schemas.network.NetworkConfigurationSchema}. Following rules are used for applying
 *            the configuration properties:
 *            <ol>
 *            <li>Specified property overrides existing one or just applies itself if it wasn't
 *            previously specified.</li>
 *            <li>All non-specified properties either use previous value or use default one from
 *            corresponding configuration schema.</li>
 *            </ol>
 *            So that, in case of initial node start (first start ever) specified configuration, supplemented with defaults, is
 *            used. If no configuration was provided defaults are used for all configuration properties. In case of node
 *            restart, specified properties override existing ones, non specified properties that also weren't specified
 *            previously use default values. Please pay attention that previously specified properties are searched in the
 *            {@code workDir} specified by the user.
