>
> Key: HIVE-29520
> URL: https://issues.apache.org/jira/browse/HIVE-29520
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Standalone Metastore
> Reporter: Venugopal Reddy K
> Assignee: Venugopal Reddy K
> Priority: Major
>
> With the increasing adoption of the Apache Iceberg table format, many
> deployments no longer rely on ACID (transactional) tables provided by Apache
> Hive. In such environments, ACID-related functionality in the Hive Metastore
> becomes unnecessary.
> Currently, Hive Metastore initializes and runs several background threads and
> services that are specifically designed to support ACID operations (e.g.,
> compaction handling, transaction management, cleanup tasks). These components
> continue to run regardless of whether ACID tables are actually used in the
> deployment.
> Running ACID-related services in environments that do not use ACID tables
> leads to:
> * Unnecessary resource consumption (CPU, memory, threads)
> * Increased operational overhead
> * Additional complexity in debugging and monitoring
> * Longer startup times and maintenance burden
> Providing a mechanism to disable ACID functionality would streamline such
> deployments and improve efficiency.
>
> *[Steps to reproduce]* **
