1. Add license/total line/release badegs.
2. Add monthly active contributor and contributor growth graph
3. fix a pom.xml bug
4. Modify some routine load log on BE side
This CL mainly changes:
1. the `storage_page_cache_limit` is based on config `mem_limit`
the default is 20% of `mem_limit`.
2. the `buffer_pool_limit` is based on config `mem_limit`
the default is 20% of `mem_limit`.
3. the `buffer_pool_clean_pages_limit` is based on config `buffer_pool_limit`
the default is 50% of `buffer_pool_limit`
4. Fix some show bugs of lru cache hit ratio and usage ratio
5. Fix a create view bug that `notEvalNondeterministicFunction` should be reset after analyze.
fix#6269
The outline of our changes is to improve our memory in case of OOM in BE and to speed up the calculation.
1. We do not need to do Aggregation in load, which has already been done in the ETL spark job.
2. Based on 1, we do not need to serialize/deserialize bitmap/HLL objects.
* Add statistics struct and Support manually inject statistics
This PR mainly developed the data structure used by statistical information
and the function of manually modifying the statistical information.
We use a statistics package alone to store statistical information,
and use the 'statistics manager' as a unified entry for statistical information.
For detailed data structure and explanation, please refer to the comments on the class.
Manually modify statistics include: Manually modify table statistics and column statistics.
The syntax is explained in the issue #6370.
* Show table and column statistics
'SHOW TABLE STATS' used to show the statistics of table.
'SHOW COLUMN STATS' used to show the statistics of columns.
Currently, only the tables and columns for setting statistics
will be displayed in the results.
Encapsulate some http interfaces for better management and maintenance of doris clusters.
The http interface includes getting cluster connection information, node information, node configuration information, batch modifying node configuration, and getting query profile.
For details, please refer to the document:
`docs/zh-CN/administrator-guide/http-actions/fe/manager/`
make doriswriter of DataX support format csv. Format csv is more simple and faster than
format json when data is simple
add property format: csv/json
add property column_separator: effect when format is csv, for example "\x01" , "^", etc...
Fix#6366
There is a bloom filter for each data page in a column which has bloom filter index.
`_has_null` flag can help to judge whether `null` exists in a data page.
If `null` value is added to a data page, `_has_null` will be set `true`.
After bloom filter for a data page finished, `_has_null`should be reset to `false` to prepare for next data page.
- Make load_parallelism configurable.
- Different clusters should be configured with different load_parallelism values.
- Some user don't know how to set load_parallelism, or don't know the best load_parallelism value.
