Package org.apache.ignite.client.handler.requests.table

Class ClientIndexGetRequest

java.lang.Object
org.apache.ignite.client.handler.requests.table.ClientIndexGetRequest
public class ClientIndexGetRequest extends Object
Client request: lookup rows by index key.

Returns a (possibly paginated) cursor of BinaryRows matching the supplied index key.

Wire layout (in order):

  • int index id;
  • tx meta (nil -> server starts an explicit RO tx);
  • BitSet column bitmap for projection (null or empty = all columns);
  • binary index-key bytes encoded as a BinaryTuple over the index columns;
  • int page size (must be positive - caps the rows-per-page in the response);
  • long client observable timestamp (used to bump the server-side timestamp tracker so a freshly started RO tx reads at a timestamp consistent with the client's view).
