Software-update: CockroachDB 1.1.4

Het team achter CockroachDB heeft versie 1.1.4 uitgebracht. Dit is een opensourcedatabase die uitermate geschikt is voor cloudomgevingen en die verschillende opties voor het opvangen van problemen biedt, dankzij de verspreide opzet. Voor meer informatie verwijzen we naar deze pagina, waar de meestgestelde vragen worden beantwoord. De bijbehorende lijst met veranderingen ziet er als volgt uit:

What's New in v1.1.4

SQL Language Changes
  • For compatibility with PostgreSQL, the transaction isolation level, transaction priority, and transaction status session variables have been renamed transaction_isolation, transaction_priority, and transaction_status. #20301
  • The IMPORT statement now supports 201 and 204 return codes from HTTP storage. #20516
Command-Line Changes
  • Client cockroach commands that use SQL (cockroach sql, cockroach node ls, etc.) now print a warning if the server is running an older version of CockroachDB than the client. Also, this and other warning messages are now clearly indicated with the "warning:" prefix. #20945
  • The cockroach sql command no longer fails when the server is running a version of CockroachDB that does not support the sql_safe_updates session variable. #20945
  • The cockroach sql command now performs client-side syntax checking automatically only if the client and server are running the same version of CockroachDB. This restriction will be lifted in CockroachDB v2.0. #21135
  • Reduced temporary disk space usage for the debug compact command. #20502
Bug Fixes
  • Improved rebalancing to make thrashing back and forth between nodes much less likely, including when localities have very different numbers of nodes. #20934
  • Fixed a scenario where a range that is too big to snapshot can lose availability even with a majority of nodes alive. #20906
  • Fixed a replica corruption that could occur if a process crashed in the middle of a range split. #20939
  • Fixed an issue where seemingly irrelevant error messages were being returned for certain INSERT statements.#20855
  • Crash details are now properly copied to the log file even when a node was started with --logtostderr as well as in other circumstances when crash details could be lost previously. #20842
  • Fixed an issue where wildcards (_, %) and \ escaped characters in LIKE patterns were not handled properly. #20654
  • Fixed the return type signature of the array_positions() built-in function. This caused a crash if the function was used in query execution by the distributed execution engine. #20652
  • Fixed a crash caused by null collated strings. #20648
  • Fixed a crash caused by NATURAL JOINS and USING in conjunction with a filter. #20582
  • Fixed build when new versions of libgtest are installed. #20598
  • Fixed a crash caused by an edge-case when queries are run against a table undergoing a schema change. #20541
  • Fixed a race condition that would result in some queries hanging after cancellation. #20534
  • Fixed a crash caused by some corner-case queries containing ORDER BY. #20512
  • Prevented generating empty sstables at the storage layer, which could cause corruption. #20284
  • Fixed a crash caused by cockroach dump in the presence of reference cycles. #20283
  • It is no longer possible to use conflicting AS OF SYSTEM TIME clauses in different parts of a query. #20286
  • Improved S3 resiliency during BACKUP/RESTORE/IMPORT. #21003
Performance Improvements
  • Improved garbage collection of very large transactions and large volumes of abandoned write intents. #20446
Enterprise Edition Changes
  • BACKUP/RESTORE jobs now support 201 and 204 return codes from HTTP storage. #20516
Doc Updates
  • Added a tutorial on orchestrating CockroachDB v1.1 with Mesosphere DC/OS. #2321
  • Improved the initial steps for troubleshooting a problem, and added a list of common errors with recommended solutions. #2311
  • Updated docs styling to increase information density. #2304
  • Documented how to request and set trial and enterprise license keys for CockroachDB. #2278
  • Fixed the placement of AS OF SYSTEM TIME in enterprise BACKUP examples. #2324
  • Updated the secure Kubernetes tutorial with RBAC support. #2281
