Problem:
When window function in aggregation function, executor would report an error like: Required field 'node_type' was not present!
Example:
SELECT SUM(MAX(c1) OVER (PARTITION BY c2, c3)) FROM test_window_in_agg;
Reason:
When analyze aggregate, analytic expr (window function carrior when analyze) transfered to slot and loss message. So when
serialize to thrift package, TExpr can not determine node_type of analytic expr.
Solved:
We do not support aggregate(window function) yet. So we report an error when analyze.
FunctionStringConcat::execute_impl resized with size that include string null terminator, which causes ColumnString::chars.size() does not match with ColumnString::offsets.back, this will cause problems for some string functions, e.g. like and regexp.
* Revert "[fix](executor) only mysql connect to set GlobalPipelineTask (#22205)"
* Revert "[feature](executor) using fe version to set instance_num (#22047)"
return empty result instead of error for empty match query as follows:
`SELECT * FROM t WHERE msg MATCH ''`
`SELECT * FROM t WHERE msg MATCH 'stop_word'`
1. Remove bunch of SQLs related to partition's information
2. Fix the duplicate SQLs submission
3. Fix bug that table's stats not get updated after system job finished
Hive file path may contain temporary directory like this:
drwxrwxrwx - root supergroup 0 2023-03-22 21:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-03-22_21-03-12_047_8461238469577574033-1
drwxrwxrwx - root supergroup 0 2023-05-18 15:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-05-18_15-03-52_780_3065787006787646235-1
This will cause error when be try to read these files. Need to filter them during FE plan.
Memtrackers are usually bound to operators in query/load. If a large number of query/loads are stuck, memtrackers will be very large. memory tracker profile refresh thread will get stuck on the lock.
This pr is for branch-2.0, I will rewrite the memory profile in the next pr
Bug：
When the value of some ES column is empty, querying these value in doc_values mode will receive an error.
Reson：
In doc values mode, these values are empty, We need to determine if the array is empty
Now we make wrong for decimal parse from string
if given string precision is bigger than defined decimal precision, we will return a overflow error, but only digit part is bigger than typed digit length , we should return overflow error when we traverse given string to decimal value
