crate 0.50.2 / 0.51.0 发布，大规模数据存储系统

crate 0.50.2 / 0.51.0 发布，其中 0.50.2 的更新内容如下：

- Fix: reduced the amount of unnecessary data handled on select queries
- Fixed an issue which prevented column updates to be noticed in the cluster on tables in custom schemas.
- Fix: issuing ``KILL ALL`` when a ``SELECT`` statement hung due to a node becoming unavailable during execution could result in error response
- Improved the error handling: In case threadpools are exhausted (due to very high load on the cluster) queries could get stuck instead of being aborted right away.
- Fixed a bug where a job entry wasn't cleaned up on any parser/analyzer errors.
- Fixed an issue that caused queries on blob tables to cause a NullPointerException if the filter in the WHERE CLAUSE resulted in a ``null`` value.
- Fix: fixed an issue which caused an error if one selects a setting which is not set
- Fix: fixed an issue which caused TypeConversion errors if a setting was selected which represents a byte size (e.g. indices[‘store’][‘throttle’][‘my_bytes_per_sec’])
- Fixed a rare bug which could cause a MapperParsingException if one creates a new dynamic array concurrently
