Thanks!
1.The seekdb supports embedded deployment and is more lightweight compared to OceanBase, making it ideal for development, validation, and small-scale production environments (suitable for scenarios that don't require large-scale distributed architecture).
2.Compared to other lightweight databases with embedded deployment capabilities, seekdb offers more comprehensive functionality with data processing capabilities fully aligned with OceanBase. It provides complete TP/AP functionality, supports vector fields up to 65,536 dimensions, custom tokenizers, and hybrid search.
3.These advantages come without additional maintenance overhead, as seekdb's interface is compatible with OceanBase, and this project already supports OceanBase.
