我正在尝试提高查询性能.对于甚至没有触及嵌套文档的简单查询,平均需要大约3秒,并且有时更长.
curl "http://searchbox:9200/global/user/_search?n=0&sort=influence:asc&q=user.name:Bill%20Smith"
即使没有那种,也需要几秒钟.以下是群集的详细信息:
1.4TB index size.
210m documents that aren't nested (About 10kb each)
500m documents in total. (nested documents are small: 2-5 fields).
About 128 segments per node.
3 nodes, m2.4xlarge (-Xmx set to 40g, machine memory is 60g)
3 shards.
Index is on amazon EBS volumes.
Replication 0 (have tried replication 2 with only little improvement)
我没有看到任何明显的CPU /内存等峰值.任何想法如何改进？
