| # Release 364 (1 Nov 2021) | ||
|
|
||
| ## General | ||
|
|
||
| * Add support for [`ALTER MATERIALIZED VIEW ... RENAME TO ...`](/sql/alter-materialized-view). ({issue}`9492`) | ||
| * Improve performance of `GROUP BY` with single grouping column. ({issue}`9514`) | ||
| * Improve performance of decimal aggregations. ({issue}`9640`) | ||
| * Improve performance when evaluating the `WHERE` and `SELECT` clause. ({issue}`9610`) | ||
| * Improve performance when computing the product of `decimal` values with precision larger than 19. ({issue}`9744`) | ||
| * Improve CPU coordinator utilization. ({issue}`8650`) | ||
| * Remove support for the `unwrap_casts` session property and `optimizer.unwrap-casts` configuration option. ({issue}`9550`) | ||
| * Fix incorrect results for queries with nested joins and ``IS NOT DISTINCT FROM`` join clauses. ({issue}`9805`) | ||
| * Fix displaying character type dynamic filter values in ``EXPLAIN ANALYZE``. ({issue}`9673`) | ||
| * Fix query failure for update operation if it has a correlated subquery. ({issue}`8286`) | ||
| * Fix decimal division when result is between `-1` and `0`. ({issue}`9696`) | ||
| * Fix [`SHOW STATS`](/sql/show-stats) failure for a query projecting a boolean column. ({issue}`9710`) | ||
|
|
||
| ## Web UI | ||
|
|
||
| * Improve responsiveness of Web UI when query history contains queries with long query text. ({issue}`8892`) | ||
|
|
||
| ## JDBC driver | ||
|
|
||
| * Allow using token from existing Kerberos context. This allows the client to perform Kerberos authentication without | ||
| passing the Keytab or credential cache to the driver. ({issue}`4826`) | ||
|
|
||
| ## Cassandra connector | ||
|
|
||
| * Map Cassandra `uuid` type to Trino `uuid`. ({issue}`5231`) | ||
|
|
||
| ## Elasticsearch connector | ||
|
|
||
| * Fix failure when documents contain fields of unsupported types. ({issue}`9552`) | ||
|
|
||
| ## Hive connector | ||
|
|
||
| * Allow to skip setting permissions on new directories by setting `hive.fs.new-directory-permissions=skip` in connector properties file. ({issue}`9539`) | ||
| * Allow translating Hive views which cast `timestamp` columns to `decimal`. ({issue}`9530`) | ||
| * Add `optimize` table procedure for merging small files in non-transactional Hive table. | ||
| Procedure can be executed using `ALTER TABLE <table> EXECUTE optimize(file_size_threshold => ...)` syntax. ({issue}`9665`) | ||
| * Restrict partition overwrite on insert to auto-commit context only. ({issue}`9559`) | ||
| * Reject execution of `CREATE TABLE` when bucketing is requested on columns with unsupported column types. | ||
| Previously `CREATE` was allowed but it was not possible to insert data to such a table. ({issue}`9793`) | ||
| * Improve performance of querying Parquet data for files containing column indexes. ({issue}`9633`) | ||
| * Fix Hive 1 and Hive 3 incompatibility with Parquet files containing `char` or `varchar` data produced by the experimental Parquet writer. | ||
| Hive 2 or newer should now read such files correctly, while Hive 1.x is still known not to read them. ({issue}`9515`, ({issue}`6377`)) | ||
| * Fix `ArrayIndexOutOfBoundsException` when inserting into a partitioned table with `hive.target-max-file-size` set. ({issue}`9557`) | ||
| * Fix reading Avro schema written by Avro 1.8.2 with non-spec-compliant default values. ({issue}`9243`) | ||
| * Fix failure when querying nested Parquet data if column indexes are enabled. ({issue}`9587`) | ||
| * Fix incorrect results when querying Parquet data. ({issue}`9587`) | ||
| * Fix query failure when writing to a partitioned table with target max file size set. ({issue}`9557`) | ||
|
|
||
| ## Iceberg connector | ||
|
|
||
| * Add support for renaming materialized views. ({issue}`9492`) | ||
| * Create Parquet files that can be read more efficiently. ({issue}`9569`) | ||
| * Improve query performance when dynamic filtering can be leveraged. ({issue}`4115`) | ||
| * Return value with UTC zone for table partitioned on `timestamp with time zone`. ({issue}`9704`) | ||
| * Fix data loss in case of concurrent inserts to a table. ({issue}`9583`) | ||
| * Fix query failure when reading from `$partitions` table for a table partitioned on `timestamp with time zone` or `uuid` ({issue}`9703`, {issue}`9757`) | ||
| * Fix query failure when reading Iceberg table statistics. ({issue}`9714`) | ||
|
|
||
| ## MemSQL connector | ||
|
|
||
| * Support reading and writing MemSQL `datetime(6)` and `timestamp(6)` types as Trino `timestamp(6)`. ({issue}`9725`) | ||
|
|
||
| ## SQL Server connector | ||
|
|
||
| * Fix query failure when `count(*)` aggregation is pushed down to SQL Server database and the table has more than 2147483647 rows. ({issue}`9549`) | ||
|
|
||
| ## SPI | ||
|
|
||
| * Expose which columns are covered by dynamic filters. ({issue}`9644`) | ||
| * Add SPI for table procedures that can process table data in a distributed manner. Table procedures can be run via `ALTER TABLE ... EXECUTE ...` syntax. ({issue}`9665`) |
