Expect vm overcommit memory value to be 1, system will no longer throw bad_alloc, memory alloc are always accepted,
memory limit check is handed over to Doris Allocator, make sure throw exception position is controllable,
otherwise bad_alloc can be thrown anywhere and it will be difficult to achieve exception safety.
When we try to query array of datetimev2 column by inverted index, it returns an error like this:

1. add session variable max_execution_time to an alias of query timeout, if user set max_execution_time, the query timeout will be modified too.
2. add a setter attribute to session variable, so that we could add some logic in setter method instead of field reflection.
Add a new FE config: show_details_for_unaccessible_tablet.
Default is false, when set to true, if a query is unable to select a healthy replica,
the detailed information of all the replicas of the tablet including the specific reason why they are unqueryable,
will be printed out.
when forbid_unknown_col_stats is open and some column stats is unknown,
we will check the be status by StatisticsUtil.statsTblAvailable(), and report error according to be status.
Fix partition field conjuncts not work.
Add predicate_partition_columns in _slot_id_to_filter_conjuncts(single slot conjuncts) to _filter_conjuncts, others should had been added from not_single_slot_filter_conjuncts.
why upgrade? anything wrong?
Try to fix the problem about opentelemetry::v1::ext::http::client::curl::HttpOperation::Send(), I have updated the pr info.
A similar situation with #19344 , because sometimes hms meta info is newer than hms events, if we try to invoke org.apache.doris.datasource.hive.PooledHiveMetaStoreClient#getTable and this table is not exists, some error will throws and this event can not be handled.
Support to gc inverted index cache when there is not enough memory.
previous problem： The inverted index cache (InvertedIndexSearcherCache and InvertedIndexQueryCache) may use 20% memory which can't be released.
1. Get DataTypeSerde in advance to avoid get temporary DataTypeSerde iterate each column
2. Iterate the original row once is enoungh for deserializing by introducing a map for record the index of each column's unique id
To be more compatible with MySQL, rename JSONB type name and function name to JSON.
The old JSONB type name and jsonb_xx function can still be used for backward compatibility.
There is a function jsonb_extract remained since json_extract is used by json string function and more work need to change it. It will be changed further.
After the outer catch exception, faststring resize reserve build may throw a memory alloc failure exception from the Allocator.
Currently page body compress will catch memory alloc failure exception
