Distribution

• Grakn's storage back-end (Cassandra) no longer throws NoSuchMethodError in cassandra.log, which previously happened continuously, resulting in a quickly growing log file.
• The console package does not depend on the server anymore, reducing the grakn-core-all distribution size from 320MB to 190MB (because the console/lib previously contained a duplicate of all jars which were also contained in server/lib).
• Removed unnecessary dependencies of Grakn server, which further reduced the distribution size from 190MB to 181MB, as the total number of external dependencies went down from 297 to 275.

Graql Execution: Read, Write, Analytics and Reasoner

• Running a query containing a negation pattern now correctly throws an exception when the query is executed with reasoner turned off (infer = false).
• Running a query with unbounded negation pattern now correctly throws an exception.
• Re-enable automatic casting of Numbers during data writes (i.e. insert queries) when the datatypes are compatible for conversion without loss of data, i.e. you can provide long/integer values where a double is expected.
• Refactored Grakn's query planner (for Graql) to be simpler and more extensible, in preparation of optimisation efforts that will be following.
