Service Registration Mechanism
As the cluster size continues to grow, the cost of cluster management will become
higher and higher. GBase 8a MPP Cluster supports the service status registration
mechanism of data computing nodes, and data computing nodes actively register
local service status to the gcware management cluster regularly. This mechanism
can improve the accuracy and timeliness of monitoring the state of data computing
nodes, and reduce the impact of a small number of abnormal nodes on the cluster.
The information registered by the Data Node to gcware includes:
The VC to which the data node belongs
A long connection session ID and node ID used for monitoring the data
node's status. After registering the session ID, gcware tracks the data
node's heartbeat, and sets its status to abnormal if the heartbeat is
interrupted.
Registration of globally consistent important parameter values, such as
gbase_compression_str_method,
gbase_compression_num_method,
and
gbase_segment_size. If the important parameters within the same VC are
inconsistent, the data computing node's service cannot be started.
