Subject Quick questions on B+ Trees and Partitions
Date Thu, 26 Jul 2018 00:07:49 GMT
Hi,


   1. B+ tree initialization, BPlusTree.initTree, seems to be called for
   every partition. Why?
   https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/persistence/tree/BPlusTree.java
   2. The documentation here,
   https://apacheignite.readme.io/docs/memory-architecture, also states
   that for each SQL index, Ignite instantiates and manages a dedicated B+
   Tree. So, is the number of B+ trees determined by partition number of # of
   indexes defined?
   3. Assume I have a Person cache and an Organization cache. How many B+
   trees are defined for each cache
   4. What differentiates one B+ tree from another B+ tree? Just the cache
   it represents?


Thanks,
John
