+Dear Community, **Apache Doris version 2.1.8 was officially released on
January 24, 2025.** This version introduces continuous upgrades and
enhancements in several key areas, including Lakehouse, Asynchronous
Materialized Views, Query Optimizer and Execution Engine, Storage Management,
and more.
+
+- [Quick Download](https://doris.apache.org/download)
+
+- [GitHub Release](https://github.com/apache/doris/releases/tag/2.1.8-rc01)
+
+## Behavior Changes
+
+- Add the environment variable `SKIP_CHECK_ULIMIT` to skip the ulimit value
verification check within the BE process. This is only available to
applications in the Docker quick start scenario.
[#45267](https://github.com/apache/doris/pull/45267)
+- Add the `enable_cooldown_replica_affinity` session variable to control the
selection of replica affinity for queries under cold - hot separation.
+- In FE, add the configurations `restore_job_compressed_serialization` and
`backup_job_compressed_serialization` to solve the OOM problem of FE during
backup and restore operations when the number of db tablets is extremely large.
Downgrading is not possible after enabling these configurations.
+
+## New Features
+
+- The Arrow flight protocol supports accessing BE through a load - balancing
device. [#43281](https://github.com/apache/doris/pull/43281)

+
+Dear Community, **Apache Doris version 2.1.8 was officially released on
January 24, 2025.** This version introduces continuous upgrades and
enhancements in several key areas, including Lakehouse, Asynchronous
Materialized Views, Query Optimizer and Execution Engine, Storage Management,
and more.
+
+- [Quick Download](https://doris.apache.org/download)
+
+- [GitHub Release](https://github.com/apache/doris/releases/tag/2.1.8-rc01)
+
+## Behavior Changes
+
+- Add the environment variable `SKIP_CHECK_ULIMIT` to skip the ulimit value
verification check within the BE process. This is only available to
applications in the Docker quick start scenario.
[#45267](https://github.com/apache/doris/pull/45267)
+- Add the `enable_cooldown_replica_affinity` session variable to control the
selection of replica affinity for queries under cold - hot separation.
+- In FE, add the configurations `restore_job_compressed_serialization` and
`backup_job_compressed_serialization` to solve the OOM problem of FE during
backup and restore operations when the number of db tablets is extremely large.
Downgrading is not possible after enabling these configurations.
+
+## New Features
+
+- The Arrow flight protocol supports accessing BE through a load - balancing
device. [#43281](https://github.com/apache/doris/pull/43281)
+- Now lambda expressions support capturing external columns
(#45186).[#45186](https://github.com/apache/doris/pull/45186)
+
+## Improvements
+
+### Lakehouse
+
+- Update the Hudi version to 0.15. And optimize the query planning performance
of Hudi tables.
+- Optimize the read performance of MaxCompute partitioned tables.
[#45148](https://github.com/apache/doris/pull/45148)
+- Support the session variable `enable_text_validate_utf8`, which can ignore
the UTF8 encoding detection in CSV format.
[#45537](https://github.com/apache/doris/pull/45537)
+- Optimize the performance of Parquet file lazy materialization under high -
filtering - rate conditions.
[#46183](https://github.com/apache/doris/pull/46183)
+
+### Asynchronous Materialized Views
+
+- Now it supports manually refreshing partitions that do not exist in an
asynchronous materialized view
[#45290](https://github.com/apache/doris/pull/45290).
+- Optimize the performance of transparent rewrite planning
[#44786](https://github.com/apache/doris/pull/44786).
+
+### Query Optimizer
+
+- Improve the adaptive ability of runtime filters
[#42640](https://github.com/apache/doris/pull/42640).
+- Add the ability to generate original column filter conditions from filter
conditions on `max/min` aggregate function columns
[#39252](https://github.com/apache/doris/pull/39252)
+- Add the ability to extract single - side filter conditions from join
predicates [#38479](https://github.com/apache/doris/pull/38479).
+- Optimize the ability of predicate derivation on set operators to better
generate filter predicates [#39450](https://github.com/apache/doris/pull/39450).
+- Optimize the exception handling ability of statistic information collection
and usage to avoid generating unexpected execution plans when collection
exceptions occur. [#43009](https://github.com/apache/doris/pull/43009)
[#43776](https://github.com/apache/doris/pull/43776)

[#42399](https://github.com/apache/doris/pull/42399)
[#41729](https://github.com/apache/doris/pull/41729)
+
+### Query Execution Engine
+
+- Optimize the execution of queries with `limit` to end faster and avoid
unnecessary data scanning [#44255](https://github.com/apache/doris/pull/44255).
+
+### Storage Management
+
+- CCR supports more comprehensive operations, such as `rename table`, `rename
column`, `modify comment`, `drop view`, `drop rollup`, etc.
+- Improve the accuracy of the broker load import progress and the performance
when importing multiple compressed files.
+- Improve the routine load timeout strategy and thread - pool usage to prevent
routine load timeout failures and impacts on queries.
+
+### Others
+
+- The Docker quick - start image supports starting without setting environment
parameters. Add the environment variable `SKIP_CHECK_ULIMIT` to skip the
`start_be.sh` script and the swap, `max_map_count`, ulimit - related
verification checks within the BE process. This is only applicable to
applications in the Docker quick - start scenario.
[#45269](https://github.com/apache/doris/pull/45269)

+- [GitHub Release](https://github.com/apache/doris/releases/tag/2.1.8-rc01)
+
+## Behavior Changes
+
+- Add the environment variable `SKIP_CHECK_ULIMIT` to skip the ulimit value
verification check within the BE process. This is only available to
applications in the Docker quick start scenario.
[#45267](https://github.com/apache/doris/pull/45267)
+- Add the `enable_cooldown_replica_affinity` session variable to control the
selection of replica affinity for queries under cold - hot separation.
+- In FE, add the configurations `restore_job_compressed_serialization` and
`backup_job_compressed_serialization` to solve the OOM problem of FE during
backup and restore operations when the number of db tablets is extremely large.
Downgrading is not possible after enabling these configurations.
+
