In the last version (9.12.0) the client introduced bigger write and read buffer sizes. The default value was 512KiB. However, users reported that this is too big for most use cases and can lead to high memory usage. In this version the default value is changed to 256KiB. The README.md was updated to reflect the correct default value and include a note that the default value can be changed.

• fix(options): Add buffer sizes to failover. Update README (#3468)
