在 Apache OAK 中,索引选择逻辑是否支持本地索引而不是全局索引?
Does the index selection logic favor local over global index in Apache OAK?
我想知道对于相同的存储库路径,索引选择逻辑是否更喜欢本地而不是全局索引定义。不幸的是,我找不到任何关于索引选择算法究竟如何工作的文档。为了使事情更清楚,请考虑以下示例:
全局定义"myIndex"
/oak:index/myIndex
- jcr:primaryType = "oak:QueryIndexDefinition"
- compatVersion = 2
- type = "lucene"
- async = "async"
- evaluatePathRestrictions = true
- queryPaths="[/content]"
- includePaths="[/content]"
+ indexRules
- jcr:primaryType = "nt:unstructured"
+ nt:unstructured
+ properties
- jcr:primaryType = "nt:unstructured"
+ code
- jcr:primaryType = "nt:unstructured"
- propertyIndex = true
- name = "myprop"
"myIndex"
的局部定义
/content/oak:index/myIndex
- jcr:primaryType = "oak:QueryIndexDefinition"
- compatVersion = 2
- type = "lucene"
- async = "async"
- evaluatePathRestrictions = true
+ indexRules
- jcr:primaryType = "nt:unstructured"
+ nt:unstructured
+ properties
- jcr:primaryType = "nt:unstructured"
+ code
- jcr:primaryType = "nt:unstructured"
- propertyIndex = true
- name = "myprop"
索引选择逻辑计算针对所有索引(本地和全局)的查询成本。评估顺序索引中第一个最便宜的索引用于查询。您可以通过 AEM 中的索引调试工具看到这一点。
