Release v0.31.0

We are delighted to bring a number of improvements to GraphScope, alongside the GraphScope 0.31.0 release. This release contains some important features and improvements to GraphScope FLEX Interactive and Groot persistent storage.

We highlight the following improvements included in this release:

1. FLEX Interactive

• String Support: We've added support for VarChar. For more information, see the String Types section in the documentation.
• Interactive Runtime Refactoring: We've refactored the implementation of the interactive runtime to enhance performance and efficiency.
• New sharding_mode Configuration: We introduced the sharding_mode configuration option. By default, Interactive will utilize the exclusive sharding mode to prevent admin requests from being blocked by long-running graph queries.
• Query Optimization: Optimized queries that follow the Scan+Limit pattern to improve execution speed and resource usage.
• Enhanced Edge Triplet Properties: Added support for multiple properties on edge triplets, allowing for more detailed data representation.
• Bug Fixes: Various bugs have been fixed to improve the stability and reliability of the system.

2. Groot persistent storage

• Support Http Gremlin Service. This service allows sending Gremlin queries via HTTP requests, with responses formatted in JSON. It adheres to the official Gremlin HTTP protocol.
• Align the data types with FLEX Interactive. For more information, see the document Data Model.
• Some bug fixes, including:
  • Fix Bugs of Getting Properties from None Entry
  • Fix Bugs of Aggregate Column Order Mismatch
  • Fix Bugs of Alias Id in Union
  • Fix Bugs of STORE_COUNT setting in Groot charts
