Enabled. Indicates whether the cluster coordinator context is enabled or not. If enabled, the cluster coordinator performs its functions in coordinating the creation, deletion, and migration of resources on the primary nodes of the cluster.
coordinatorEnabled
Coordinator Cache Type. Defines the type of cache used by the cluster coordinator. It can be either an Embedded Ignite Service or a Client Connection to an external Ignite database.
cacheType
Coordinator Cache Properties. Specifies connection properties for the cache used by the cluster coordinator.
Properties for Embedded Ignite Service cache type:
Cluster Coordinator Node Name. Indicates the unique ID of the Ignite cluster node. A random ID is generated if not specified.
Storage Path. Specifies a file system path for cached data. A relative path is interpreted as a subfolder of Iotellect Server installation folder.
Number of Backups. Indicates the number of Ignite partition backups to be maintained for data in the cluster coordinator’s cache. If you configure 2 backup copies, the Ignire cluster maintains 3 copies of each partition. Backup partitions increase the availability of data, and in some cases, the speed of read operations, since Ignite reads data from backed-up partitions if they are available on the local node. However, they also increase memory consumption and the size of the persistent storage (if enabled).
Cluster Coordinator Node Addresses. Must contain IP addresses or hostnames of all other cluster coordinator Ignite nodes.
Properties for Client Connection cache type:
Address. IP address or hostname used for client connections to an external Ignite cluster. This should be normally an address of an IP load balancer that distributes load among Ignite cluster nodes.
Port. Port number used for connecting to the external Ignite cluster.
cacheTable
Storage Type. Indicates the type of persistent data storage used by the coordinator. Options are either an Embedded Ignite Service, or Coordinator SQL Storage.
storageType
Storage Properties. Properties for configuring and connecting to the specified coordinator storage.
Properties for Embedded Ignite Service storage type:
Connection URL. Specifies the JDBC URL for connecting to Ignite node.
JDBC Driver Class. Specifies the JDBC driver to use. Default value should not be changed in most cases.
Pool Minimum Size. Sets the minimum number of connections in the connection pool.
Pool Maximum Size. Sets the maximum number of connections in the connection pool.
Pool Increment. Specifies the number of additional connections to create when pool needs to expand.
Additional Properties. Table of extra configuration options.
Properties for Coordinator SQL Storage storage type:
Connection URL. Specifies the JDBC URL for connecting to a relational storage database.
JDBC Driver Class. Specifies the JDBC driver to use.
Database Username. Login name for authentication and authorization on the database server.
Database Password. Password associated with the above username.
Database SQL Dialect. Indicates the specific SQL dialect used by the database.
Pool Minimum Size. Sets the minimum number of connections in the connection pool.
Pool Maximum Size. Sets the maximum number of connections in the connection pool.
Pool Increment. Specifies the number of additional connections to create when pool needs to expand.
Additional Properties. Table of extra configuration options.
