Grakn Core 1.5.3

on GitHub

• Server no longer hangs if you try to stop it with unclosed connections from some clients (5143)
• When you stop Console, it will now terminate the connection to Server gracefully (5144)
• Server has an improved handling of client requests coming in parallel, increasing responsiveness (5153) Thanks to this, it is now possible to issue Ctrl+C in the grakn console to interrupt long running queries.
• Server no longer leaves a dangling session when a client abruptly terminates the connection (5158)
• Server properly rejects executing bootup commands that are wrong, e.g, grakn server start stor (5159)
• Console's editor command for Windows now works properly (5166)
• Inferred concepts no longer being silently persisted if we commit a transaction that creates them, resolving issue 5136. (5142)
• Enhance performance by caching answers from queries within the same transactions. (5131)
• Improve performance by removing an expensive log call in Reasoner (5160)
• Fix issues with unification of reflexive relations (5152)
• Refactor equivalence and unification of relation atoms (5155)
• During the QP refactors done previously, indexed fragments were sometimes ordered after the variable's first occurence in the plan, which may have resulted in some slower plans. Now we explicltly put the indexed fragments at the start of the query plan again. (5151)
• Refactor role compatibility checking when unifying relations (5168)
• Differentiate semantic and query exceptions so that we handle them in a way that's more informative (for users) and faster to debug (for devs) (5170)
• Fix issue where two queries differing only by the fact that a role variable was returned (~userdefined) were treated as equivalent which lead to invalid cache entries. (5174)
• Fix issues when calculating semantic difference when roles are variable (5171)
• Correctly acknowledge role expansion answers (5173)
• Server now prints informative exception logs if an error occurs during keyspace retrieval or deletion (5167)
• Removed some performance measurement codes which are no longer used (5149)
• Adds auto-syncing which will automatically update Grakn KGMS to always depend on the latest Grakn Core (5141)
