Zhiting Guo updated KYLIN-5945:
-------------------------------
Description:
Kylin's metadata has some architectural issues, such as: #
1. The metadata adopts a key-value structure. The JSON block contains a lot of
content, which will grow with the growth of customer business, resulting in
excessive network IO when updating metadata.
#
The design of epoch and project lock ensures that transactions within the
project are executed serially, resulting in single-point bottlenecks and
concurrency problems.
