Control Center 2023.4 Release Notes
What’s New in This Release
Introduction
GridGain® Control Center is a comprehensive, customizable cluster management and developer tool for Apache® Ignite™ and GridGain applications. Use Control Center to query data across caches, monitor performance metrics, define and track production alerts, take snapshots for backup and recovery, and collect and analyze API traces. The latest Control Center 2023.4 release includes a number of UX and bug fixes.
New Features
Data Center Replication Dashboards
This release of Control Center includes two new dashboards, which jointly reflect the data center replication (DR) process:
-
DR Sender - this tab displays statistics that pertain to the sender nodes participating in the DR. The widgets include:
-
Queue - a metric line chart that enables you to detect issues in the DR process
-
Replication progress - a multi-metric line chart that provides a quick overview of the overall health and performance of the DR process
-
Nodes - a table that helps you examine the DR topology and receiver node configurations
-
Caches - a table that helps you examine the replicated cache configurations and the replication status per cache (you can display a cache’s configuration via the context menu)
-
Remote Receiver Connections - a table that lists connections defined between sender and receiver clusters (data centers)
-
-
DR Receiver - this tab displays statistics that pertain to the receiver nodes participating in the DR process. It includes the following widgets:
-
Queue - a metric line chart that enables you to detect issues in the DR process
-
Replication progress - a multi-metric line chart that provides a quick overview of the overall health and performance of the DR process
-
Nodes - a table that helps you examine the DR topology and receiver node configurations
-
Remote Senders - a table that lists the clusters (data centers) that serve as senders to the current receiver cluster
-
This feature is available with GridGain version 8.8.x starting from 8.8.37, as well as with GridGain 8.9.x version starting from 8.9.1.
Scan Queries
This release adds the UI controls for defining, running, and viewing the results of, scanning queries. A scan query is used to retrieve data from a cache in a distributed manner. When executed without parameters, the scan query returns all entries from the cache.
You can now initiate a scan query on a specific cache (selected either in the Queries List tab or in the Cashes screen. You can run the query with or without advanced settings - a specific node, partition number, amd a set of regex expressions.
The query results are shown on the screen and can be exported to a CSV file.
This feature is available with GridGain version 8.8.x starting from 8.8.37, as well as with GridGain 8.9.x version starting from 8.9.1.
Binary Type Management
This release of Control Center enables binary type management via the UI. GridGain prohibits changing a column type (e.g. INT to VARCHAR or even LONG) in both SQL tables and caches, due to the Binary Object format limitations. To work around this limitation, you can now remove and restore (as well as view and download) a binary type’s metadata (and all the data of that type) using the new Binary type management tab in the Control Center UI. Previously, this functionality was available only via the control.sh --meta commands.
This feature is available with GridGain version 8.8.x starting from 8.8.36, as well as with GridGain 8.9.x version starting from 8.9.1.
