Running parallel business logic on the data grid (DataGrid
API)
The DataGrid API provides a simple programming interface
to run business logic over all or a subset of the data grid in parallel
with where the data is located.
DataGrid APIs and partitioning
With the DataGrid APIs, a client can send requests to one
partition, a subset of partitions, or all the partitions in a data
grid. The client can specify a list of keys, and WebSphere® eXtreme Scale determines the set
of partitions that are hosting the keys. The request is then sent
to all the partitions in the set in parallel and the client waits
for the results. The client can also send requests without specifying
keys, therefore, requests are sent to all partitions.
