Good catch. I found the ticket that’s aim is to integrate the full-text search indexes with the virtual page memory architecture. https://issues.apache.org/jira/browse/IGNITE-5371 Sergi, do we have a similar one for the geo-spatial? — Denis

Same think stays for the full-text indexes which are currently stored in Lucene. 2017-05-24 21:56 GMT+03:00 Dmitriy Setrakyan : > Sergi, > > While we are figuring this out, what happens to the GeoSpatial > functionality in the mean time? Is it going to work at all? If not, should > we throw some

Sergi, While we are figuring this out, what happens to the GeoSpatial functionality in the mean time? Is it going to work at all? If not, should we throw some sort of exception? D. On Wed, May 24, 2017 at 1:44 AM, Sergi Vladykin wrote: > Though this may require some changes in BPlusTree. Let m

It must not be too hard to implement kd-tree over b+tree [1]. Depending on level we have to compare either X or Y coordinate. I think we will even have a performance boost for spatial indexes after this change. [1] https://en.wikipedia.org/wiki/K-d_tree Sergi 2017-05-23 18:59 GMT+03:00 Denis Ma

+1 This looks natural considering that we switched to the new memory architecture. Sergi, how difficult is to support this? — Denis > On May 23, 2017, at 4:25 AM, Sergi Vladykin wrote: > > Guys, > > Looks like we have to move our geospatial indexes to the new approach with > BPlusTree. Right

Geo spatial index

2017-05-23 Thread Sergi Vladykin
Guys, Looks like we have to move our geospatial indexes to the new approach with BPlusTree. Right now it stores data in Java heap. This is especially important because we are going to have a persistence layer donated by GridGain and obviously geo spatial indexes will not work with it at all. Serg
