get_read_batch_size()

int hazelcast::client::config::reliable_topic_config::get_read_batch_size

(

)

const

Gets the maximum number of items to read in a batch.

Returned value will always be equal or larger than 1.

Returns

the read batch size.

Definition at line 366 of file config.cpp.

                                                                 {
                return read_batch_size_;
            }

set_read_batch_size()

reliable_topic_config & hazelcast::client::config::reliable_topic_config::set_read_batch_size

(

int

batch_size

)

Sets the read batch size.

The ReliableTopic tries to read a batch of messages from the ringbuffer. It will get at least one, but if there are more available, then it will try to get more to increase throughput. The minimal read batch size can be influenced using the read batch size.

If the readBatchSize is 10 and there are 50 messages available, 10 items are retrieved and processed consecutively.

If the readBatchSize is 10 and there are 2 items available, 2 items are retrieved and processed consecutively.

Parameters

readBatchSize

the maximum number of items to read in a batch.

Returns

the updated reliable topic config.

Exceptions

illegal_argument

if readBatchSize is smaller than 1.
