Cache List
The Cache list tab — monitoring active GridGain 8 caches, their replication state, and the cache management actions available from Control Center.
The Cache list tab displays a list of all active caches. You can copy this data or export it to a CSV file.
By default, the list includes the following columns:
Name
The cache name.
Mode
See Data Partitioning.
Atomicity
See Atomicity Modes.
Statistics
Whether statistics gathering for the cache is enabled or disabled.
Replication
Whether the cache participates in data replication (DR) (ON/OFF).
Sender group
The name of the sender group the cache belongs to. Relevant if Replication=ON.
Replication state
The incremental data replication state (STOPPED/WORKING). Relevant if Replication=ON.
FST state
The state of the full state transfer (WORKING/FAILED). Relevant if Replication=ON.
FST Statistic
Shows the total number of entries transferred for this cache during the last finished FST. In-progress FST is not included. FST statistic is collected only while Control Center is online
Total keys
The total number of keys stored in the cache.
Primary keys
The number of primary keys stored in the cache. Hidden by default. Add via the list's context menu.
Backup keys
The number of backup keys stored in the cache. Hidden by default. Add via the list's context menu.
The leftmost column of the list offers check boxes that you use to select multiple caches for enabling or disabling statistics (see cache management options below).
You can:
Add or remove columns to/from the list by selecting or deselecting column names in the list's context menu.
Filter the cache list by any of its columns using the Filters pane on the right.
To manage a cache, use that cache's context menu. The menu contains the following items:
Enable statistics
Enables collection of cache statistics. You can enable statistics for multiple caches at a time using the check boxes to select caches.
Disable statistics
Disables collection of cache statistics. You can disable statistics for multiple caches at a time using the check boxes to select caches.
Show partition distribution
Redirects to the Partition Distribution tab with the corresponding information on partition distribution of the selected cache.
Show lost partitions
Redirects to the Lost Partitions tab with the corresponding information on lost partitions (if any) of the selected cache.
Show cache configuration
Opens the read-only Cache Configuration dialog. See Configure Caches for more details.
Load from cache store
Executes the cache.loadCache() method for the selected cache to preload data from the underlying database into memory.
Run rebalance
Starts rebalance process. See Data Rebalancing for more details.
Run scan query
Opens a new Scan query tab in the Queries screen and runs a scan query on the selected cache with all the advanced options set to default values.
Remove all
Deletes all entries from the cache via removeAll(). If DR is enabled, deletions will be propagated to the remote cluster. See this page to choose the correct method for your environment.
Clear
Clears cache entries locally via clear(). If DR is enabled, deletions will not be propagated. See this page to choose the correct method for your environment.
Destroy selected cache
Removes the cache.
Pause replication
Pauses the DR process.
Resume replication
Resumes the previously paused DR process.
Start full state transfer
Starts the full state transfer process. In clusters that support targeting specific data centers, one or more data center IDs are required before initiating a transfer; otherwise, it will run on all remote receivers.
Stop full state transfer
Stops the full state transfer process.
When running Start full state transfer for clusters that support targeting specific data centers, you must select one or more DC ID from the list.
