+ Building the materialized view function for schema_change here based on defineExpr.
+ This is a trick because the current storage layer does not support expression evaluation.
+ count distinct materialized view will set mv_expr with to_bitmap or hll_hash.
+ count materialized view will set mv_expr with count.
+ Support to regenerate historical data when a new materialized view is created in BE。
+ Support to_bitmap function
+ Support hll_hash function
+ Support count(field) function
For #3344
The output columns of query should be collected by all of tupleIds
in BaseTableRef rather than the top tupleIds of query.
The top tupleIds of count(*) is Agg tuple which does not expand the star.
Fixed#4065
Resource release should be done by dest RowBatch.
When we call method transfer_resource_ownership.
if we don't clear the corresponding resources,
which will cause the core problem of double delete.
[Bug]Fix some schema change not work right
This CL mainly fix some schema change to varchar type not work right
because forget to logic check && Add ConvertTypeResolver to add
supported convert type in order to avoid forget logic check
[Bug] Fix the problem of mem exec, when analytic eval node need to spill to disk with a low mem limit.
And clear_reservations of Analytic node reservation of block manager.
[Running Profile] Add Spilled flag in Running Profile, when Analytic eval node and sort node spill to Disk.
This PR is mainly to add `thrift_client_retry_interval_ms` config in be for thrift client
to avoid avalanche disaster in fe thrift server and fix some typo and some rpc
setting problems at the same time.
fix#4047#3886 has certain relevance to this case。
the sql : `bigtable t1 join mysqltable t2 join mysqltable t3 on t1.k1 = t3.k1`
1. after reorder:
t1, t2, t3
2. choose join t1 with t2:
t1 join t2 with no conditions, and Doris choose cross join
3. choose join (t1 join on t2) with t3:
in old code, the t2 is mysqlTable, so the cardinality is zero,
and "the cross join t1 with t2" 's cardinality is t1.cardinality multiply t2.cardinality,
for t2 is mysql, so t2.cardinality is zero, and "the cross join t1 with t2" is zero.
t3 is mysqltable, t3's cardinality is zero.
**If two tables need to be joined both are zero，we will choose the shuffle join**
So I change the mysql table ‘s cardinality from 0 to 1, the cross join's cardinality is not zero.
1. Doris support modify char to varchar. There is a bug when use two-level pointer when converting the date.
2. Boolean can be used as metric value with REPLACE and REPLACE_IF_NOT_NULL aggregation function. The aggregation function should be added into aggregation map.
Its time to enable some features by default.
1. Enable FE plugins by setting `plugin_enable=true`
2. Enable dynamic partition by setting `dynamic_partition_enable=true`
3. Enable nio mysql server by setting `mysql_service_nio_enabled=true`
Also modify installation doc, add download link of MySQL client.
This CL mainly changes:
1. Reorganized the code logic to limit the supported json format to two, and the import behavior is more consistent.
2. Modified the statistical behavior of the number of error rows when loading in json format, so that the error rows can be counted correctly.
3. See `load-json-format.md` to get details of loading json format.
Fixes#3995
## Why does it happen
When SetOperations encounters that the previous node needs Aggregate, the timing of add AggregationNode is wrong. You should add AggregationNode first before add other children.
## Why doesn't intersect and union have this problem
intersect and union conform to the commutation law, so it doesn't matter if the order is wrong
## Why this problem has not been tested before
In the previous test case, not cover the previous node was not AggregationNode
After PR #3454 was merged, we should refactor and reorganize some logic for long-term sustainable iteration for Doris On ES.
To facilitate code review，I would divided into this work to multiple PRs (some other WIP work I also need to think carefully)
This PR include:
1. introduce SearchContext for all state we needed
2. divide meta-sync logic into three phase
3. modify some logic processing
4. introduce version detect logic for future using
This CL mainly support set replication_num property in dynamic partition
table if dynamic_partition.replication_num is not set, the value is the
same as table's default replication_num.
Now, FE use ThreadPoolManager to manage and monitor all Thread,
but there are still some threads are not managed. And FE use `Timer` class
to do some scheduler task, but `Timer` class has some problem and is out of date,
It should replace by ScheduledThreadPool.
Doris only support TThreadPoolServer model in thrift server, but the
server model is not effective in some high concurrency scenario, so this
PR introduced new config to allow user to choose different server model
by their scenario.
Add new FE config: `thrift_server_type`
TPlanExecParams::volume_id is never used, so delete the print_volume_ids() function.
Fix log, and log if PlanFragmentExecutor::open() returns error.
Fix some comments
We can build unit tests by specify BUILD_TYPE to DEBUG/RELEASE/LSAN/ASAN,
and outputs in each mode will be placed to different directories, it will
save time if rebuild in a same mode.
fix: https://github.com/apache/incubator-doris/issues/3984
1. add `conjunct.size` checking and `slot_desc nullptr` checking logic
2. For historical reasons, the function predicates are added one by one, I just refactor the processing make thelogic for function predicate processing more clearly
