Ah OK. that's the batch size for inbound API calls to Segment. You don't need to worry about this. The min and max batch sizes are you are setting relate to how many payloads will be passed into the performBatch() function. This should be based off of how many payloads the Customer.io API can handle. So if Customer.io is able to handle up to 1000 events per batch, then we would set the max to 1000, and maybe the default also. Can you find this out please, and amend the PR? Thanks, Joe

Each of the requests within the batch must also be 32kb or smaller. So for max_batch size i am considering the edge case where all the requests in the batch are 32 kb which gives us 15 for the max_batch size. I do am unsure if this works do let me know what more can i do to confirm this number — Reply to this email directly, view it on GitHub <https://urldefense.com/v3/__https://github.com/segmentio/action-destinations/pull/3106*discussion_r2235478680__;Iw!!NCc8flgU!euG77E2jZKPFEHSfOjO0-Aql6zRRExuhYcaQ23f6jxFVGJgbIyaQc6pEL1r_lbqrNH_Oh7bgVIxkCadYk40YbRRvuQ$>, or unsubscribe <https://urldefense.com/v3/__https://github.com/notifications/unsubscribe-auth/AK2F3MCD3HPLN6CPIVQU7Y33KXSHZAVCNFSM6AAAAACCI5CUI6VHI2DSMVQWIX3LMV43YUDVNRWFEZLROVSXG5CSMV3GSZLXHMZTANRRGQYTONZQGU__;!!NCc8flgU!euG77E2jZKPFEHSfOjO0-Aql6zRRExuhYcaQ23f6jxFVGJgbIyaQc6pEL1r_lbqrNH_Oh7bgVIxkCadYk40icb49hw$> .
