索引所有字段是否对 Solr 有负面影响？
Does indexing all fields have a negative effect on Solr?
我有一个 Solr 云（7.4 版），有 2 个节点和 10 个 collections。这是我的 managed-schema 之一：

我的 collections 有 10 亿个文档。
我可以 Index 和 Docvalues 所有字段吗？。这对 read 或 write 查询有负面影响吗？
Can I Index and Docvalues All Fields?
是的，当然可以。
Does this have a negative impact in read or write query?
您索引或启用文档值的每个字段都有成本。通过启用 index/docValues，索引会更大，索引（写入）更慢。在查询端（阅读）你通常会更快（你不能在你没有索引的字段中搜索，但是 docValues 对于许多操作来说不是必需的并且可以提高它们的查询性能）。
与往常一样，您需要找到一个平衡点。如果您的 collections 很大（10 亿大），您通常只在绝对需要的字段中启用 index/docValues。如果一切正常，也许您接下来可以启用一些您想要的字段，然后反复测试
