Elasticsearch OutOfMemoryError索引文檔時的Java堆空間

Question

我正在嘗試將3個文檔編入索引。 我已經能夠成功索引前兩個索引，但是在索引第三個索引時，我收到與終端中堆空間有關的錯誤。 我嘗試將jvm.options文件中的堆大小增加到3g，因為我只有4GB的RAM，但仍然沒有幫助 。 這是我的文檔的樣子，並且以前索引的文檔僅在坐標值發生變化的情況下才與之相似：

curl -XPUT 'localhost:9200/test/test1/2?pretty&pretty' -H 'Content-Type: application/json' -d'

索引映射

curl -XPUT 'localhost:9200/test/?pretty' -H 'Content-Type: application/json' -d'

}}}}}}'

Answer 1

我可以通過將索引映射的精度從1m更改為2m來解決此問題。 由於我的RAM位於下側，因此對空間索引的精度要求較低。
