Download CockroachDB 2.0.2
What’s New in v2.0.2
General Changes
- The header of new log files generated by cockroach start will now include the cluster ID once it has been determined. # 24982
- The cluster ID is now reported with tag [config] in the first log file, not only when log files are rotated. # 24982
- Stopped spamming the server logs with “error closing gzip response writer” messages. # 25108
SQL Language Changes
- Added more ways to specify an index name for statements that require one (e.g., DROP INDEX, ALTER INDEX … RENAME, etc.), improving PostgreSQL compatibility. # 24817
- Clarified the error message produced upon accessing a virtual schema with no database prefix (e.g. when database is not set). # 24809
- STORED is no longer a reserved keyword and can be used as an unrestricted name for databases, tables and columns. # 24864
- Errors detected by SHOW SYNTAX are now tracked internally like other SQL errors. # 24900
- IMPORT now supports hex-encoded byte literals for BYTES columns. # 25063
- Collated strings can now be used in WHERE clauses on indexed columns. # 25175
- The Level and Type columns or EXPLAIN (VERBOSE) results are now hidden; if they are needed, they can be SELECTed explicitly. # 25206
Admin UI Changes
- Added RocksDB compactions / flushes to storage graphs. # 25457
Bug Fixes
- It is once again available in selected stars (e.g., SELECT mydb.kv. * FROM kv) for compatibility with CockroachDB v1.x. # 24842
- Fixed a scenario in which could deadlock while starting up. # 24831
- Ranges in partitioned tables are now properly split to respect their configured maximum size. # 24912
- Some child or schedule change errors that were stuck in a permanent loop now correctly fail. # 25015
- When adding a column, CockroachDB now verifications that the column is referenced by no more than one foreign key. Existing tables with a column that is used by multiple foreign key constraints should be changed at least one foreign key per column. # 25079
- CockroachDB now properly reports an error when using the internal-only functions final_variance () and final_stddev () instead of causing a crash. # 25218
- The constraint_schema column in information_schema.constraint_column_usage now displays the constraint’s schema instead of its catalog. # 25220
- Fix a panic caused by some queries containing OFFSET and ORDER BY. # 25238
- START; RELEASE SAVEPOINT now returns an error instead of causing a crash. # 25251
- Fixed a rare segfault returned from C ++. # 25361
- Fixed a bug with IS DISTINCT NOT returning NULL values that pass the condition in some cases. # 25339
- Restarting a CockroachDB server on Windows no longer fails due to file system locks in the store directory. # 25439
- Prevented the consistency checker from deadlocking. This would have been the case as a steady number of replicas for consistency checking on one or more nodes. # 25474
- Fixed problems with IMPORT sometimes failing after node decommissioning. # 25307
- Fixed a bug causing PREPARE to hang when the CREATE TABLE statement. # 24874
Build Changes
- Build metadata, like the commit SHA and build time, is properly injected into the binary when using Go 1.10 and building from a symlink. # 25062
Doc Updates
- Improved the documentation of the now (), current_time (), current_date (), current_timestamp (), clock_timestamp (), statement_timestamp (), cluster_logical_timestamp (), and age () built-in functions. # 25383 # 25145
