休眠搜索：Elasticsearch 传输线程-3

Question

我正在使用带有 elasticsearch 的休眠搜索作为我的索引管理器。目前，我的 jvm 设置为使用 1gb 内存，我不希望增加内存。

我有一个@Transactional类为索引的 .csv 文件总共插入了 200 万行@Entity。

尽管插入成功，但 lucene 索引器内存不足导致事务回滚。下面是我的休眠搜索配置和异常堆栈跟踪：

hibernate.search.default.indexmanager = elasticsearch

elastic= hibernate.search.default.elasticsearch.host =http://localhost:9200

hibernate.search.default.elasticsearch.index_schema_management_strategy = CREATE

#should be green for prod

hibernate.search.default.elasticsearch.required_index_status = yellow

hibernate.search.elasticsearch.scroll_backtracking_window_size=10000

hibernate.search.elasticsearch.scroll_fetch_size=1000

堆栈跟踪：

是否有任何调整可以帮助缓解这种情况？
