我在Elasticsearch索引中有一个字段,其中包含以下映射
"cluster_boundary": {
"type": "geo_shape",
"tree": "quadtree",
"precision": "1mm"
}
但是当我将此映射放在elasticsearch索引中时,我收到以下错误
java.lang.IllegalArgumentException: maxLevels of 36 exceeds limit of 29

如果我将quadtree
更改为geohash
则可行。而且,根据elasticsearch,quadtree
中允许的最大树级别为50
。
答案 0 :(得分:2)
PackedQuadPrefixTree
的最高级别为29,而QuadPrefixTree
的最高级别为50.您可以检查here和here。
我浏览了ES source code。 quadtree
映射到lucene PackedQuadPrefixTree
,因此您必须将精度值降低到1m
,转换为26个tree_levels,或者您可以使用最多50个级别的legacyquadtree
。
如果您使用out of memory error
指定非常多的级别而不是说最大允许级别为50,那么我注意到的一件事是ES抛出legacyquadtree
。
PUT test_index/_mapping/test_type
{
"properties": {
"test": {
"type": "geo_shape",
"tree": "legacyquadtree",
"tree_levels": "54354552"
}
}
}
理想情况下,上面的代码应该说最大级别是50,但是它会耗尽堆空间并抛出OOM错误。
我也认为1mm太精确了,即使使用leagcyquadtree也会占用大量内存。 More就此而言。我还在github上打开了一个issue,您可以关注它。
