Examples with ModelStorage org.apache.ignite.ml.inference.storage.model.ModelStorage used on opensource projects

Example 1 with ModelStorage

use of org.apache.ignite.ml.inference.storage.model.ModelStorage in project ignite by apache.

the class IgniteModelStorageUtil method saveModelEntity.

/**
 * Saves specified serialized model into storage as a file.
 *
 * @param ignite Ignite instance.
 * @param serializedMdl Serialized model represented as a byte array.
 * @param mdlId Model identifier.
 */
private static void saveModelEntity(Ignite ignite, byte[] serializedMdl, UUID mdlId) {
    ModelStorage storage = new ModelStorageFactory().getModelStorage(ignite);
    storage.mkdirs(IGNITE_MDL_FOLDER);
    storage.putFile(IGNITE_MDL_FOLDER + "/" + mdlId, serializedMdl, true);
}

Example 2 with ModelStorage

use of org.apache.ignite.ml.inference.storage.model.ModelStorage in project ignite by apache.

the class IgniteModelStorageUtil method removeModelEntity.

/**
 * Removes model with specified identifier from model storage.
 *
 * @param ignite Ignite instance.
 * @param mdlId Model identifier.
 */
private static void removeModelEntity(Ignite ignite, UUID mdlId) {
    ModelStorage storage = new ModelStorageFactory().getModelStorage(ignite);
    storage.remove(IGNITE_MDL_FOLDER + "/" + mdlId);
}
