索引所有字段是否会对Solr产生负面影响？

Question

我有一个Solr云（版本7.4），包含2个节点和10个集合。这是我的managed-schema之一：

我的藏品有10亿份文件。我可以Index‍和Docvalues所有领域吗？这对read或write查询有负面影响吗？

Answer 1

我可以索引和Docvalues所有字段吗？

是的，确定你可以。

这对读取或写入查询有负面影响吗？

索引或启用docvalues的每个字段都有成本。通过启用index / docValues，索引将更大，索引（写入）更慢。在查询方面（读取），您通常会更快（您不能在未编制索引的字段中搜索，但docValues对于许多操作不是必需的，并且可以改善它们的查询性能）。

一如既往，你需要找到一个平衡点。如果您的馆藏很大（10亿大），通常只在您绝对需要的字段中启用索引/ docValues。如果一切正常，也许您可​​以在下一个想要的字段中启用，并迭代测试
