Speeding up In-Memory Joins using Join Groups
What are Join Groups?
A new In-Memory feature called Join Groups was introduced with the Database In-Memory Option in Oracle Database 12.2. Join Groups can be created to significantly speed up hash join performance in an In-Memory execution plan. Creating a Join Group involves identifying up-front the set of join key columns (across any number of tables) likely to be joined with by subsequent queries. For example, the following join group object connects EMP and DEPT tables with their respective deptno join key columns:
create inmemory join group JG (EMP(deptno), DEPT(deptno));
After the creation of the join group, populating the tables involved in the join group will result in a single domain dictionary built that join keys from the join columns specified in the Join Group are mapped to. By pre-defining and storing a single map across…

NVThe problem-solving principle known as “Occam’s razor” states that the simplest solution is usually the best one.[1] Essentially, this type of thinking helps explain the growing interest in Non-Volatile Memory Express (NVMe) over an Ethernet environment. Adoption rates are accelerating for mobile and social systems of engagement, big data and real time analytics, and many […]
