过去几周我一直在尝试解决这个问题。索引工作“完美”，直到它不。它经常与大量的实体（10 k+），在所有实体的70%左右，它开始抛出403响应。

设置

休眠配置：

cfg.setProperty("hibernate.search.backend.aws.region",config.getProperty("AWS_REGION"))

代码：

CompletableFuture.runAsync {
    Search.session(database.factory.openSession())
        .massIndexer()
        .idFetchSize(20)
        .batchSizeToLoadObjects(10)
        .dropAndCreateSchemaOnStart(false)
        .purgeAllOnStart(false)
        .startAndWait()
}

输出：

一开始......工作正常：

我已经看了所有我能找到的文档，尝试了不同的参数，偏移量，fetchId大小，等等，但是没有用。真正的区别因素，我似乎不能挖掘通过是第一次工作（实体实际上是索引和显示），但它不工作后，一段时间...（4- 5分钟）。什么都没有找到。
欢迎任何反馈、回答或问题。
