fastrtps::ResourceLimitedContainerConfig matched_publisher_allocation

Matched publishers allocation limits.

fastrtps::ResourceLimitedContainerConfig sample_infos_allocation = {32u}

SampleInfo allocation limits.

int32_t max_samples_per_read = 32

Maximum number of samples to return on a single call to read / take.

This attribute is a signed integer to be consistent with the max_samples argument of DataReader methods, but should always have a strict positive value. Bear in mind that a big number here may cause the creation of the DataReader to fail due to pre-allocation of internal resources.

Default value: 32.
