UPGRAGDE NOTICE

If you are using a CubeFS version earlier than v3.5.0, please refer to the UPGRADE NOTICE in version v3.5.0 for detailed upgrade steps and upgrade to v3.5.0 first.

Main Feature

• all: flash cache in cluster. （#2943 @bboyCH4, @longerfly, @slasher, @shuqiang-zheng, @clinx）
• flash: scale out the cache layer by adding more cache nodes to handle increased read traffic.
• master: save the FlashNode topology state and push FlashNode topology data to the client.
• client: data reads are routed to the appropriate cache node based on consistent hashing.
• cli: use CLI commands to query the current cache status and control its behavior.

Enhance

• data/meta: support for dynamic adjustment of gogc. (#3816, @shuqiang-zheng)
• client: actively release part of the client's memory to reduce memory footprint. (@bboyCH4)
• client: support reading data with quorum consistency. (@zhumingze1108)

Bugfix

• meta: tune the retry mechanism for failed volume creation to minimize the impact on volume deletion performance. (@bboyCH4)
• data: no longer allow single replica dp raftForce deletion. (@zhumingze1108)
• data: add CRC check for extent ID allocation. (@leonrayang)
• client: monitor already contains grouping label commit. (@zhumingze1108)
• client: failure to update the local extent cache generation resulted in an LTP failure.(@bboyCH4)
• flash: Removing an fn immediately after a single 200ms timeout on origin fetch is too sensitive. A better approach would be to remove it only after multiple consecutive timeouts. (@longerfly)
• object: copy data between different buckets. (@clinx)
