There is a bug in this release that will cause queries with the predicate
IS NULL on
bucketed columns to produce incorrect results.
Fix failures caused by invalid plans for queries with repeated lambda expressions in the order by clause.
Fix accounting of raw input bytes in ScanFilterAndProjectOperator.
Fix an issue where server fails to start when two function namespace managers of the same type are specified.
Fix SQL function compilation error when input parameters contain lambda.
IS DISTINCT FROMfor long decimals.
Improve error handling for geometry deserialization edge cases.
Improve performance of
Improve efficiency of
ST_Buffer(). The new implementation produces fewer buffer points on rounded corners, which will produce very similar but different results. It also better handles buffering with small (<1e-9) distances.
Improve OOM killer log output to put memory heavy nodes and queries first.
Improve efficiency by using JTS instead of Esri for many geometrical operations and fix incorrect calculation of extreme points in certain cases (#14031).
Add forms of
approx_percentile()accepting an accuracy parameter.
Add a new session property
aggregation_partitioning_merging_strategyto configure partition merging strategy when adding exchange around aggregation node (#11262).
IGNORE NULLSclause to various Window Functions.
Fix schema mismatch with Parquet
Improve string column stats by including the sum of all strings’ lengths when the individual min/max of the string is too long in ORC writer.
Allow reading data from HDFS while caching the fetched data on local storage. Turn on the feature by specifying the cache directory config
Add support for parallel partition fetching for the Glue metastore.
Add support for the AWS Default Credentials Provider for S3.
Add the ability to read and write with delta deletes.
Fix an issue where checksum query text and ID are not recorded if the checksum query fails.
Improve verifier to skip verification when checksum query fails to compile.
Add checks for the cardinalities sum when validating an array column.
Add new columns
verifier_queries, and remove column
session_properties_json. The value of the removed column can be copied to the two new columns for the schema change.
Add details of determinism analysis runs to the output.
Add configuration property
max-determinism-analysis-runsto control maximum number of determinism analysis runs in case of column mismatch.
Add configuration property
run-teardown-for-determinism-analysisto allow disabling teardown for determinism analysis runs.
Add API to check if the query is unexpectedly modified using the credentials passed in the identity.
