+ <p>Apache Iceberg handles dynamically changing data at large scale.
However, frequent modifications
+come at a cost: eventually, tables will become fragmented. This degrades the
performance of read
+operations over time. To address this challenge, we introduced table
maintenance features in Apache
+Impala, the high performance, distributed DB engine for big data.</p>
+<p>The new OPTIMIZE statement merges small data files and eliminates delete
files to uphold table
+health. It allows rewriting the table according to the latest schema and
partition layout, and also
+offers the flexibility of file filtering to optimize recurring maintenance
jobs. Additionally, the
+DROP PARTITION statement allows selective partition removal based on
predicates.</p>
+<p>Discover in this session how Impala ensures high performance on top of
dynamically changing data.</p>

+ <p>Sizing Virtual compute clusters for diverse and complex workloads is
hard. Queries often require
+large clusters to meet SLA requirements which can lead to low utilization and
excessive cloud spend.
+To solve this problem, we present intelligent autoscaling for Impala virtual
warehouses. This
+powerful feature dynamically analyzes query execution plans and resource
requirements and adjusts
+cluster size to follow the workload. Once cluster size limits have been set,
the autoscaler works in
+the background to maintain the ideal cluster size and is transparent to users.
Observability UIs
+have also been enhanced to help understand autoscaler behavior and further
tune workloads.</p>
+<p>We achieved 2 key goals with the design - delivering better ROI for compute
cost and ease of use for
+admins/users to manage Virtual Clusters.</p>

+ <p>Apache Impala is a horizontally scalable database engine renowned for
its emphasis on query
+efficiency. Over recent years, the Impala team has dedicated substantial
effort to support Iceberg
+tables. Impala can read, write, modify, and optimize Iceberg tables.
Additionally, it facilitates
+schema and partition evolution through DDL statements.</p>
+<p>Attendees can anticipate a comprehensive overview of all Iceberg-related
features within Impala,
+along with insights into forthcoming developments expected this year. Given
Impala's Java/C++ hybrid
+architecture — where the frontend, responsible for analysis and planning, is
Java-based while
+backend executors are coded in C++ — the integration process encountered its
own set of challenges.
+This presentation will delve into some details of this integration work,
shedding light on the
+technical nuances.</p>

+ <p>Apache Iceberg handles dynamically changing data at large scale.
However, frequent modifications
+come at a cost: eventually, tables will become fragmented. This degrades the
performance of read
+operations over time. To address this challenge, we introduced table
maintenance features in Apache
+Impala, the high performance, distributed DB engine for big data.</p>
+<p>The new OPTIMIZE statement merges small data files and eliminates delete
files to uphold table
+health. It allows rewriting the table according to the latest schema and
partition layout, and also
+offers the flexibility of file filtering to optimize recurring maintenance
jobs. Additionally, the
+DROP PARTITION statement allows selective partition removal based on
predicates.</p>
+<p>Discover in this session how Impala ensures high performance on top of
dynamically changing data.</p>

- <p>Impala has proven to be a high-performance analytics query engine since
the beginning. Even as an
-initial production release in 2013, it demonstrated performance 2x faster than
a traditional DBMS,
-and each subsequent release has continued to demonstrate the wide performance
gap between Impala’s
-analytic-database architecture and SQL-on-Apache Hadoop alternatives. Today,
we are excited to
-continue that track record via some important performance gains for Impala 2.5
(with more to come on
-the roadmap), summarized below.</p>
-
-<p>Overall, compared to Impala 2.3, in Impala 2.5:</p>
-
-<ul>
-<li>TPC-DS queries run on average 4.3x faster.</li>

+ <p>Apache Impala is a horizontally scalable database engine renowned for
its emphasis on query
+efficiency. Over recent years, the Impala team has dedicated substantial
effort to support Iceberg
+tables. Impala can read, write, modify, and optimize Iceberg tables.
Additionally, it facilitates
+schema and partition evolution through DDL statements.</p>
+<p>Attendees can anticipate a comprehensive overview of all Iceberg-related
features within Impala,
+along with insights into forthcoming developments expected this year. Given
Impala's Java/C++ hybrid
+architecture — where the frontend, responsible for analysis and planning, is
Java-based while
+backend executors are coded in C++ — the integration process encountered its
own set of challenges.
+This presentation will delve into some details of this integration work,
shedding light on the
+technical nuances.</p>

+ <p>Sizing Virtual compute clusters for diverse and complex workloads is
hard. Queries often require
+large clusters to meet SLA requirements which can lead to low utilization and
excessive cloud spend.
+To solve this problem, we present intelligent autoscaling for Impala virtual
warehouses. This
+powerful feature dynamically analyzes query execution plans and resource
requirements and adjusts
+cluster size to follow the workload. Once cluster size limits have been set,
the autoscaler works in
+the background to maintain the ideal cluster size and is transparent to users.
Observability UIs
+have also been enhanced to help understand autoscaler behavior and further
tune workloads.</p>
+<p>We achieved 2 key goals with the design - delivering better ROI for compute
cost and ease of use for
+admins/users to manage Virtual Clusters.</p>

+
+Apache Iceberg handles dynamically changing data at large scale. However,
frequent modifications
+come at a cost: eventually, tables will become fragmented. This degrades the
performance of read
+operations over time. To address this challenge, we introduced table
maintenance features in Apache
+Impala, the high performance, distributed DB engine for big data.
+
+The new OPTIMIZE statement merges small data files and eliminates delete files
to uphold table
+health. It allows rewriting the table according to the latest schema and
partition layout, and also
+offers the flexibility of file filtering to optimize recurring maintenance
jobs. Additionally, the
+DROP PARTITION statement allows selective partition removal based on
predicates.
+
+Discover in this session how Impala ensures high performance on top of
dynamically changing data.

+
+Apache Impala is a horizontally scalable database engine renowned for its
emphasis on query
+efficiency. Over recent years, the Impala team has dedicated substantial
effort to support Iceberg
+tables. Impala can read, write, modify, and optimize Iceberg tables.
Additionally, it facilitates
+schema and partition evolution through DDL statements.
+
+Attendees can anticipate a comprehensive overview of all Iceberg-related
features within Impala,
+along with insights into forthcoming developments expected this year. Given
Impala's Java/C++ hybrid
+architecture — where the frontend, responsible for analysis and planning, is
Java-based while
+backend executors are coded in C++ — the integration process encountered its
own set of challenges.
+This presentation will delve into some details of this integration work,
shedding light on the
+technical nuances.

Queries often require
+large clusters to meet SLA requirements which can lead to low utilization and
excessive cloud spend.
+To solve this problem, we present intelligent autoscaling for Impala virtual
warehouses. This
+powerful feature dynamically analyzes query execution plans and resource
requirements and adjusts
+cluster size to follow the workload. Once cluster size limits have been set,
the autoscaler works in
+the background to maintain the ideal cluster size and is transparent to users.
Observability UIs
+have also been enhanced to help understand autoscaler behavior and further
tune workloads.
+
+We achieved 2 key goals with the design - delivering better ROI for compute
cost and ease of use for
+admins/users to manage Virtual Clusters.
