Ultimate Performance Having been polished for years, the driver is close to a native JDBC in terms of efficiency, with ultimate performance. • Ecosystem Compatibility The proxy can be accessed by any application requirements. 7.1.2 Limitations Currently only Java language is supported. 7.1.3 Requirements The development environment requires Java JRE 8 or later. 7.1.4 Procedure 1. Rules configuration. Please refer introduced new problems while gaining benefits. One of the major challenges is that application development engineers and database administrators become extremely overwhelmed with all these operations after

Consistency of Container Images • Container images are used throughout the life cycle of software development – Dev – Test – Staging – Production • Consistency must be maintained – Version control often keep images within their own organizations – Intellectual property stays in organization – Efficiency: LAN vs WAN • People with different roles should have different access – Developer – Read/Write key component to manage images • Organizations usually need a private registry – Security – Efficiency 35 Harbor���������� • ����������Harbor���� v1.1+����� • ����Harbor���������� ����� �������������
