Limits for codecs in spring

I was getting following exception while using Web Client.

org.springframework.core.io.buffer.DataBufferLimitException: Exceeded limit on max bytes to buffer : 262144

which indicated that codec limit has to be increased via MaxInMemorySize property.

I wanted to understand if MaxInMemorySize is set to X, does that mean for every request our application puts aside X amount of memory for buffering upfront or that the memory is assigned dynamically as per the response size of each request.

I faced a similar error updating the below property in spring-boot application.yml helped resolve this error.

spring:
  codec:
    max-in-memory-size: 700KB

you can change the default DataBufferLimit using the above property.

Spring maintains some amount of buffer which is MaxInMemorySize (around 250KB). This can be modified by adding a property to the application.properties / application.yml.

example:

spring.codec.max-in-memory-size: 10MB

By adding this, the max in memory size will be increased to 10MB.

Coming to your question, since this is a predefined value, the spring internally creates some buffer rather than creating individually for each request.
