Release notes
14.3
Date: 29.06.2023
The new monitoring system is implemented. Added the Metrics storage service that can collect metrics from multiple ADPG clusters. For information on the installation of the new monitoring system, refer to Install monitoring |
ADCM UI now contains the following monitoring cluster settings: Use external ADPG cluster for monitoring, External ADPG cluster [ip_address:port], Monitoring db name, Monitoring username, and Monitoring user password |
The following settings of the new Metrics storage service are available in ADCM UI: Monitoring db name, Monitoring username, Monitoring user’s password, Grafana TCP port, and Grafana admin’s password |
Since the new built-in monitoring system is implemented, ADPG no longer supports the integration with the Monitoring cluster. If you want to upgrade to version ADPG 14.3.4 from previous versions via automatic updates, you have to configure the monitoring system manually. If you upgrade from ADPG Community 14.3.4 to Enterprise 14.3.4, you also need to configure monitoring manually, since the Community version does not support load balancing, which is necessary for monitoring |
Date: 16.03.2023
Load balancing is implemented in ADPG Enterprise edition. The new Balancer service performs balancing based on HAProxy |
ADCM UI now contains Balancer service settings: leader as replica, leader_port, replica_port, and balancer_stats_port |
The contrib and PostGIS extensions are included in ADPG and do not require installation |
Since the contrib and PostGIS extensions are included in the ADPG distribution, the settings and actions related to their installation are removed |
You can upgrade to version 14.3.3 from version 14.3.2. If you need to upgrade from an earlier version, upgrade first to 14.3.2 and then to 14.3.3 |
| Issue | Workaround |
|---|---|
If you add nodes to expand the Etcd service, new nodes are not included in the ADPG cluster configuration |
To solve the problem, you need to execute the Reconfigure & Reload action of the ADPG service and Reconfigure & Restart of the Balancer service |
Date: 29.12.2022
High availability (HA) feature based on Patroni is implemented in ADPG Enterprise Edition |
The Etcd service required for HA is added |
The ADCM UI now contains External Etcd settings that allow you to use an external Etcd cluster as an alternative of the built-in Etcd service |
The Check, Disable maintenance mode, Enable maintenance mode, and Expand actions are implemented for services |
The ADCM UI now includes the following Patroni ADPG configuration settings: synchronous_mode, synchronous_node_count, synchronous_mode_strict, and maximum_lag_on_failover |
The Enable monitoring setting and the Install monitoring agents action are added for the ADPG cluster. These options install monitoring agents on all hosts of the cluster |
Offline installation is implemented in ADPG Enterprise Edition |
Upgrade an ADPG cluster from a previous version to version 14.3.2 does not preserve the settings specified in postgresql.conf custom section. It is necessary to restore them manually |
Date: 30.06.2022
ADPG migrates to PostgreSQL 14.3. For information about changes and migration to PostgreSQL 14.3, see PostgreSQL release notes |
Alt Linux 8.4 SP is supported |
Base monitoring system is implemented |
The following performance tuning options are added to the ADCM UI: effective_cache_size, maintenance_work_mem, work_mem, min_wal_size, max_wal_size, wal_keep_size, huge_pages, and superuser_reserved_connections |

Date: 28.04.2022
The ADPG_v14.2_arenadata1 bundle is created. It is the ADCM-integrated Open-Source PostgreSQL bundle for the x86-architectures (RHEL 7, CentOS 7). The bundle is designed to install two services: ADPG and Chrony. The following rpm-packages are used:
|
The ADCM integration for the ADPG installation and administration is implemented |
The Install, Reinstall, Delete, and Uninstall actions are implemented for the Chrony service in ADCM |
The ability to perform minor updates of the ADPG bundle version via ADCM is implemented |
The ability to add lines to the pg_hba.conf file via ADCM is added. To do this, it is necessary to fill in the PG_HBA custom section in the ADPG service configuration window and then apply the Reconfigure & Reload action |
The Run SQL action is implemented for the ADPG service in ADCM |
The Install postgis action is implemented for the ADPG service in ADCM |
The Install contrib action is implemented for the ADPG service in ADCM |
The Start and Stop actions are implemented for the ADPG service and cluster in ADCM |
The Check action is implemented for the ADPG cluster in ADCM |
The Precheck action is implemented for the ADPG cluster in ADCM |
The Install and Reinstall actions are implemented for the ADPG service in ADCM |
