Elasticsearch 2.3地理形状类型映射

我在Elasticsearch索引字段与以下映射Elasticsearch 2.3地理形状类型映射

"cluster_boundary": { 
     "type": "geo_shape", 
     "tree": "quadtree", 
     "precision": "1mm" 
    }

但是当我把这个映射中的elasticsearch指数出现以下错误

如果我将quadtree更改为geohash它的工作原理。并且，根据elasticsearch，quadtree中的最大允许树级别为50。

的最高水平可能PackedQuadPrefixTree是29而QuadPrefixTree是50.您可以检查here和here。

我翻看了ES source code。 quadtree映射到lucene PackedQuadPrefixTree因此您必须将精度值降低到1m，这可以转化为26个树型级别，或者您可以使用最大为50级的legacyquadtree。

有一两件事我注意到的是ES抛出out of memory error如果你指定，而不是说允许的最大水平非常高的数字与legacyquadtree水平为50

PUT test_index/_mapping/test_type 
{ 
    "properties": { 
    "test": { 
     "type": "geo_shape", 
     "tree": "legacyquadtree", 
     "tree_levels": "54354552" 
    } 
    } 
}

理想上面的代码应该说最高等级是50，但它耗尽堆空间并抛出OOM错误。

我也认为1mm太精确了，即使有leagcyquadtree它也会占用大量的内存。 More就此。我也在github上打开了一个issue，你可以关注它。

感谢您的回复。按照elasticsearch的文档'''quadtree'''最多有50个级别。根据你所说的文件似乎是错误的。我会尝试使用'''legacyquadtree'''。我已经尝试过'''1m'''的精度，而树的水平是'''33'''。 –
