New features and improvements
You can now choose between two different storage modes:
Transactional mode - the default database mode that favors
strongly-consistent ACID transactions using WAL files and periodic
snapshots, but requires more time and resources during data import and
analysis.
Analytical mode - speeds up import and data analysis but offers no ACID
guarantees besides manually created snapshots.
Switch between modes within the session using the STORAGE MODE IN_MEMORY_{TRANSACTIONAL|ANALYTICAL}; query. #772
You can now call subqueries inside existing queries using the CALL clause. #794
When you want to filter data using properties that all have label:property
indexes set, you can make Memgraph analyze the properties on all or several
labels with the ANALYZE GRAPH; query. By calculating the distribution of
property values, Memgraph will be able to select the optimal index for the
query and it will execute faster. #812
If, for example, you are no longer interested in the results of the query you
ran, or the procedure you built is running in an infinite loop, you can stop
the transaction with the TERMINATE TRANSACTIONS tid; query; Find out the
transaction ID with SHOW TRANSACTIONS; query. #790
With the new flag password-encryption-algorithm you can choose between bcrypt, sha256, and sha256-multiple encryption algorithms. SHA256 offers
better performance compared to the more secure but less performant bcrypt. #839
Import using the LOAD CSV clause has been further improved by
Bugfixes
The users who have global visibility on the graph will experience a slight
improvement in performance regarding label-based access control as the engine
no longer check privileges for each node. #837
The All shortest paths algorithm now supports multiedges. #832
