Release Notes: v0.7.0

We are glad to announce the availability of GraphScope v0.7. This release includes major updates for the persistent graph store in GraphScope, providing APIs for real-time graph updates (inserts and deletes of individual vertices and edges). It also focuses on user-friendly improvements, security issues, code quality, and a series of bug fixes.

We highlight the following improvements included in this release:

1. Apart from bulk loading, this release introduces a set of APIs for real-time graph updates. Currently, these APIs have supported the following functions:
   • Insert/delete one or multiple vertices/edges;
   • Update properties of a specific vertex/edge.

   More details can refer to this.

2. User-friendly improvement
   • Revise error handling in GraphScope and improve all error messages reported to users;
   • Add a document to describe persistent graph store in GraphScope;
   • The logs in the err channel are always fetched to the client for debugging;
   • The bulk-loading tool of the persistent graph store is released to help load graphs into the store;
   • Revise some descriptions for APIs in documents.
3. Optimizations and enhancements
   • Using zetcd to replace zookeeper in the graph interactive engine;
   • Update third-party dependencies to address some security issues;
   • More test coverages for GAIA and client;
   • Integrate GIE GraphManager into Coordinator;
   • During sess.gremlin, the pod will not be created dynamically for reducing the response time.
4. Some Breaking API Changes:
   • Remove GIE GraphManager role;
   • Remove zookeeper and replace with zetcd;
   • k8s_gie_graph_manager_image, k8s_gie_graph_manager_cpu, k8s_gie_graph_manager_mem Deprecated;
   • k8s_zookeeper_image, k8s_zookeeper_cpu, k8s_zookeeper_mem Deprecated;
   • k8s_gie_gremlin_server_cpu, k8s_gie_gremlin_server_mem Deprecated.
