Question

我正在尝试通过以下StreamVisitor：

将数据流式传输到Ignite

val streamer = ignite.dataStreamer[ProductKey, Product]("products")
streamer.allowOverwrite(true)
streamer.autoFlushFrequency(100)

streamer.receiver(new StreamVisitor[ProductKey, Product] {
    val atomic = ignite.atomicLong(s"version@${input.inventoryId}", 0L, true)

    def apply(cache: IgniteCache[ProductKey, Product], entry: Entry[ProductKey, Product]): Unit = {
        def updateProduct(key: ProductKey, product: Product): Unit = {
            val version = atomic.incrementAndGet()
            println(s"Updating product ${product.productId} to version $version")
            cache.put(key, product.copy(version = version))
            //                versionChangeQueue.add(VersionChange(product.inventoryId, version))
        }

        val key = entry.getKey
        val product = entry.getValue
        val current = cache.get(key)
        if (current == null) {
            updateProduct(key, product)
        } else {
            if (attributesDiffer(product.attributes, current.attributes)) {
                updateProduct(key, product)
            } else {
                println(s"Product ${product.productId} hasn't changed")
            }
        }
    }

    private def attributesDiffer(newAttributes: Map[UUID, String], oldAttributes: Map[UUID, String]): Boolean = {
        newAttributes exists {
            case (id, value) => oldAttributes.getOrElse(id, "") != value
        }
    }
})

我反复addData然后flush。即使我看到了这一点：

18:31:04.672 INFO  o.a.i.i.m.d.GridDeploymentLocalStore - Class locally deployed: class io.livefeeds.api.pull.PullWorker$$anon$1

我经常会遇到以下例外：

服务器日志说：

这里究竟出了什么问题？

Answer 1

这里的问题似乎是关闭Regex rgx = new Regex("^([Gg][Ii][Rr] 0[Aa]{2}|([A-Za-z][0-9]{1,2}|[A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2}|[A-Za-z][0-9][A-Za-z]|[A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z]) ?[0-9][A-Za-z]{2})$");实例。我在部署到服务器的JAR中创建了一个独立的Ignite类，其中包含FeedVisitor。但是，独立类也可以使用对等类加载。

为什么我的Ignite数据流不合格？
