Fix a bug that JDBC catalog/database/table should be add to GsonUtil
Fix a class loader issue that sometime it will cause ClassNotFoundException
Fix regression test to use different catalog name.
Comment out 2 regression tests:
regression-test/suites/query_p0/system/test_query_sys.groovy
regression-test/suites/statistics/alter_col_stats.groovy
Need to be fixed later
When a user has multiple catalogs and switch several times, he may forget which catalog is using. So I add a iscurrent column in show catalogs result for help.
mysql> show catalogs;
+-----------+-------------+----------+-----------+
| CatalogId | CatalogName | Type | IsCurrent |
+-----------+-------------+----------+-----------+
| 136591 | es | es | |
| 130100 | hive | hms | yes |
| 0 | internal | internal | |
+-----------+-------------+----------+-----------+
* merge proj-proj
* v2this pr guarantees that the physical plan does not contains consecutive physical projects.
Like rewrite rule "merge projects", it works on physical plan, not logical plan.
* move merge-proj code into Project.java
Fix two things:
1. Fix that the MySQL table displays the garbled code even if the UTF8 is specified for table.
2. Fix that `test_mysql_jdbc_catalog.out` lack of returned data for table `ex_tb13`.
1.remove quick_compaction's rowset pick policy, call cu compaction when trigger
quick compaction
2. skip tablet's compaction task when compaction score is too small

1. fix NPE exception #14740
2. fix issue:
mysql> alter catalog xyz set properties ('hive.metastore.uris'='thrift://172.21.0.1:7004');
ERROR 1105 (HY000): errCode = 2, detailMessage = Can't modify the type of catalog property with name: xyz
3. change behavior. The original logic is use props in set properties clause to replace all exists props, now change to only replace the listed props in set properties clause, and new props will be added. Make it behavior like alter table property stmt.
1. Map muiltiple tasks to one Job
2. Remove the codes for analyzing whole default db, since this feature is not available and would create too many tasks and related code is confusing
3. support analyze materialized view
4. abstract the common logic to BaseTask
Add an event producer, channel, consumer system to support the feature as title and you can turn it on using set
enable_nereids_event = true;
For more information, please see fe/fe-core/src/main/java/org/apache/doris/nereids/metrics/README.md
In the k8s environment, the ip of the pod can be changed, but the hostname of pod is stable. When the host machine of the pod fails, the k8s can schedule the failed pod to the new host machine for reconstruction. After that, the newly created pod's hostname remains unchanged, and the ip address has been changed. The change of the be node's ip address can be detected by FQDNManager when enable_fqdn_mode is true
