# Which issue does this PR close? <!-- We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes #123` indicates that this PR will close issue #123. --> Closes #6094. # Rationale for this change StringView users will by default benefit from exponential block size growth to keep the buffer count low. <!-- Why are you proposing this change? If this is already explained clearly in the issue then this section is not needed. Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes. --> # What changes are included in this PR? I try to make the change simple unless we have a reason for more complexed implementation. My justification: - I would like to keep the size of builder small, previously 212 bytes, now it is 216 bytes (+4). Large builder is less memory efficient and make me hesitate to use builder on performance critical code. - Currently the largest size is 2MB, starting size is 8KB. Although those are fixed values, I think they should cover most of the use cases. If users want larger size, they would go with the Fixed strategy. <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> # Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!--- If there are any breaking changes to public APIs, please add the `breaking change` label. --> -- This is an automated message from the Apache Git Service.
