This commit changes the behavior: if load_balance_mode= off in streaming replication mode, now all the user queries are sent to the primary server only.
A partition is a data arrangement unit between clusters for managing the data movement to adjust the load balance between nodes and data multiplexing(replica) in case of a failure.
An Ingress may be configured to give Services externally-reachable URLs, load balance traffic, terminate SSL/ TLS, and offer name based virtual hosting.
Smallest data arrangement unit among clusters, and data movement and replication unit for adjusting the load balance between nodes(rebalancing) and for managing data replicas in case of failure.
If a SELECT query is inside an explicit transaction block, replicate_select and load_balance_mode will have an effect on how replication works.
Smallest data placement unit between clusters and data movement and replication unit for adjusting the load balance between nodes(rebalance) and for managing the data multiplexing(replica) in case of a failure.
Please note that using logical backup and PITR should be performed directory PostgreSQL, rather than via pgpool-II to avoid errors caused by load_balance_mode and replicate_select.
For user's convenience,"show pool_nodes" command shows the session local load balance node info since this is important for users in case of failover.
The application was shown to have very good computational load balance, but it was recommended that some improvements should be made in the area of the MPI based communications code.
This will disable the load balance of the particular query and Pgpool-II will send it to the master node(the primary node in Master Slave mode).
A Load Balance Warning will appear if you attempt to connect to a server that is loaded more than 30% of another server in the same location.
Disable load balance after a SELECT having functions specified in black function list or not specified in white function list.(Bo Peng).
Ixia's visibility architecture was used to connect to inline and out-of-band security and network monitoring tools to the network, filter and load balance data to the tools, and deliver high availability solutions for inline tools.
In a typical scenario, there is a lot of open memory space spread across a cluster, and such a technique can load balance memory usage across many servers.
However if other than primary node or master node returns an error state(this could happen if load balance node is other than primary or master node and the query is an errornous SELECT), this should be returned to frontend, because the frontend already received an error.
After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node(this is not clear from the report but I confirmed it in my investigation).
In addition to that, set master_slave_mode and load_balance_mode to true.
In addition to integrating with big data operation analysis technology in cloud computing, we can combine Smart Gateway with container technology through the integration and management of Kubernetes with high availability(HA) and load balance(LB), to drive the high performance of Edge computing.
For example, in a 16 Disk system, instead of a 16 Disk RAID 6 where all the drive heads have to seek together to find files, or instead of two separate RAID 5 volumes with disparate files and directory paths, DDP can load balance any volume across two 8 Disk RAID5/6.
Load balance heavy traffic to multiple monitoring tools.
