Use sessions to interact with data, including insert and
update operations.
About this task
The
ObjectMap interface has
the typical Map operations such as put, get, and remove. However,
use the more specific operation names such as: get, getForUpdate,
insert, update, and remove. These method names convey the intent more
precisely than the traditional Map APIs.
Note: The
upsert and
upsertAll methods replace the ObjectMap
put and
putAll methods. Use the
upsert method to tell the BackingMap that an entry in the data grid needs to place the key and value into
the grid. The BackingMap does
either an insert or an update to place the value into the grid .
You can also use the indexing support, which is flexible.
