avoid hitting disk you need more RAM. On a standard mechanical drive you can handle graphs with a few tens of millions of primitives (nodes, relationships and properties) with 2-3 GBs of RAM. A server with 8-16 GBs of RAM can handle graphs with hundreds of millions of primitives, and a good server with 16-64 GBs can handle billions of primitives. However, if you invest in a good SSD you will be able to handle much larger graphs on less RAM.<\/p>\n<\/blockquote>\n<p>\u3064\u307e\u308a\u3001RAM 16-64 GB \u3067\u657010\u5104\u4ef6\u3092\u51e6\u7406\u3067\u304d\u308b\u305d\u3046\u3067\u3059\u3002100GB\u7a4d\u3081\u3070\u304d\u3063\u3068\u5927\u4e08\u592b\u3068\u4fe1\u3058\u305f\u3044\u3068\u3053\u308d\u3067\u3059\u3002<\/p>\n<h2>[\u53c2\u8003] Community\u30a8\u30c7\u30a3\u30b7\u30e7\u30f3 or Enterprise\u30a8\u30c7\u30a3\u30b7\u30e7\u30f3<\/h2>\n<p>\u4eca\u56de\u306f<code>Community\u30a8\u30c7\u30a3\u30b7\u30e7\u30f3<\/code>\u3067\u306a\u3093\u3068\u304b\u5927\u4e08\u592b\u3068\u5224\u65ad\u3057\u307e\u3057\u305f\u3002<\/p>\n<p><a href=\"https:\/\/neo4j.com\/subscriptions\/#editions\">\u3053\u3061\u3089<\/a>\u306b\u4e8c\u3064\u306e\u30a8\u30c7\u30a3\u30b7\u30e7\u30f3\u306e\u9055\u3044\u304c\u66f8\u3044\u3066\u3042\u308a\u307e\u3059\u3002\u7279\u306b\u6c17\u306b\u306a\u3063\u305f\u306e\u306f\u3001\u4ee5\u4e0b\u4e8c\u70b9\u3067\u3059\u3002<\/p>\n<ul>\n<li>Cluster<\/li>\n<li>Graph size limitations: 34B nodes<\/li>\n<\/ul>\n<p>\u4eca\u56de\u306f\u3001\u30b0\u30e9\u30d5\u306e\u30ea\u30ec\u30fc\u30b7\u30e7\u30f3\u3092\u7e4b\u3050\u3068\u3053\u308d\u3060\u3051\u3092Neo4j\u3067\u884c\u3063\u3066\u3001\u7d50\u679c\u30c7\u30fc\u30bf\u3092\u6052\u4e45\u7684\u306b\u7ba1\u7406\u3059\u308b\u306e\u306f\u3042\u304f\u307e\u3067BigQuery\u3067\u884c\u3046\u3053\u3068\u3092\u8003\u3048\u3066\u3044\u308b\u305f\u3081\u3001Clusteing\u3067\u304d\u306a\u304f\u3066\u5927\u4e08\u592b\u3068\u5224\u65ad\u3057\u307e\u3057\u305f\u3002<\/p>\n<p>\u30ce\u30fc\u30c9\u6570\uff08\u304a\u305d\u3089\u304f\u30ea\u30ec\u30fc\u30b7\u30e7\u30f3\u6570\u3082\uff09\u304c340\u5104\u4ef6\u306e\u5236\u9650\u3082\u3001\u898b\u7a4d\u3082\u308a\u4e0a\u306f\u30ae\u30ea\u30ae\u30ea\u53ce\u307e\u308b\u306f\u305a\u3067\u3059\u3002<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u3084\u308a\u305f\u3044\u3053\u3068 \u5019\u88dc\u30ce\u30fc\u30c9\uff08\u7d041\u5104\u4ef6\uff09\u3068\u5019\u88dc\u540c\u58eb\u306e\u30ea\u30ec\u30fc\u30b7\u30e7\u30f3\uff08\u7d04100\u5104\u4ef6\uff09\u3092neo4j\u306b\u767b\u9332\u3057\u3066\u3001\u7279\u5b9a\u306e\u6761\u4ef6\u3067\u7e4b\u304c\u3063\u3066\u3044\u308b\u30b5\u30d6\u30b0\u30e9\u30d5\u306e\u30ce\u30fc\u30c9ID\u3092\u62bd\u51fa\u3057\u305f\u3044\u3068\u601d\u3044\u307e\u3059\u3002 \u5165\u529b\u30c7\u30fc\u30bf \u5019\u88dc1 &#8212; \u5019\u88dc2 (score = 40) \u5019\u88dc1 &#8212; \u5019\u88dc3 (score = 60) \u5019\u88dc3 &#8212; \u5019\u88dc4 (score = 50) \u5019\u88dc4 &#8212; \u5019\u88dc5 (score = 70) \u5019\u88dc6 &#8212; \u5019\u88dc7 (score = 30) \u5019\u88dc7 &#8212; \u5019\u88dc8 (score = 70) \u5019\u88dc9 &#8230; \u30ea\u30ec\u30fc\u30b7\u30e7\u30f3\u306a\u3057 score\u306f\u95a2\u9023\u6027\u306e\u5f37\u3055\u3067\u3059\u3002\u672c\u6765\u3001\u95a2\u9023\u6027\u306b\u65b9\u5411\u306f\u3042\u308a\u307e\u305b\u3093\u3002 \u30b0\u30e9\u30d5\u8868\u793a\u3059\u308b\u3068\u3053\u3093\u306a\u30a4\u30e1\u30fc\u30b8\u3067\u3059\u3002 \u3053\u306e\u30c7\u30fc\u30bf\u304b\u3089\u30af\u30a8\u30ea\u3067score &gt;= 50\u4ee5\u4e0a\u306e\u30ea\u30ec\u30fc\u30b7\u30e7\u30f3\u3092\u63a5\u5408\u3057\u3066\u3001\u4ee5\u4e0b\u306e\u3088\u3046\u306a\u30c7\u30fc\u30bf\u3092\u53d6\u5f97\u3057\u305f\u3044\u3068\u601d\u3063\u3066\u3044\u307e\u3059\u3002 [\u5019\u88dc1, \u5019\u88dc3, \u5019\u88dc4, \u5019\u88dc5] [\u5019\u88dc2] [\u5019\u88dc6] <a href=\"http:\/\/localhost:8000\/2020\/03\/neo4j-python-subgraph.html\" class=\"read-more button-fancy -red\"><span class=\"btn-arrow\"><\/span><span class=\"twp-read-more text\">Continue Reading<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[31,7],"tags":[],"_links":{"self":[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/posts\/296"}],"collection":[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/comments?post=296"}],"version-history":[{"count":1,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/posts\/296\/revisions"}],"predecessor-version":[{"id":297,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/posts\/296\/revisions\/297"}],"wp:attachment":[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/media?parent=296"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/categories?post=296"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/tags?post=296"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
