Amazon Kinesis Client Library for Python

Python interface for the Amazon Kinesis Client Library (KCL) MultiLangDaemon, enabling Python applications to process Kinesis streams using the KCL's multi-language protocol. Current version 3.1.3 (October 2025), with major version 3 introducing breaking changes from v2 (e.g., mandatory dual-stack endpoint support, removed checkpoint manager customizations). The library wraps Java KCL via a subprocess (MultiLangDaemon). Releases follow the upstream KCL Java library cadence.
