[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
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.
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.
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.
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`

* fix ut
* add doc

Fix: #3946
CL:
1. Add prepare phase for `from_unixtime()`, `date_format()` and `convert_tz()` functions, to handle the format string once for all.
2. Find the cctz timezone when init `runtime state`, so that don't need to find timezone for each rows.
3. Add constant rewrite rule for `utc_timestamp()`
4. Add doc for `to_date()`
5. Comment out the `push_handler_test`, it can not run in DEBUG mode, will be fixed later.
6. Remove `timezone_db.h/cpp` and add `timezone_utils.h/cpp`
The performance shows bellow:
11,000,000 rows
SQL1: `select count(from_unixtime(k1)) from tbl1;`
Before: 8.85s
After: 2.85s
SQL2: `select count(from_unixtime(k1, '%Y-%m-%d %H:%i:%s')) from tbl1 limit 1;`
Before: 10.73s
After: 4.85s
The date string format seems still slow, we may need a further enhancement about it.
Currently we choose BE random without check disk is available,
the create table will failed until create tablet task is sent to BE
and BE will check is there has available capacity to create tablet.
So check backend disk available by storage medium will reduce unnecessary RPC call.
1. Split /_cluster/state into /_mapping and /_search_shards requests to reduce permissions and make the logic clearer
2. Rename part es related objects to make their representation more accurate
3. Simply support docValue and Fields in alias mode, and take the first one by default
#3311
Fix#3920
CL:
1. Parse the TCP metrics header in `/proc/net/snmp` to get the right position of the metrics.
2. Add 2 new metrics: `tcp_in_segs` and `tcp_out_segs`
When starting FE with `start_fe.sh --helper xxx` command, do not allow to
point helper to FE itself. Because this is meaningless and may cause some
confusing problemes.
This configuration is specifically used to limit timeout setting for stream load.
It is to prevent that failed stream load transactions cannot be canceled within
a short time because of the user's large timeout setting.
This CL mainly support timezone in dynamic partition:
1. use new Java Time API to replace Calendar.
2. support set time zone in dynamic partition parameters.
This plugin is used to output data to Doris for logstash
Use the HTTP protocol to interact with the Doris FE Http interface
Load data through Doris's stream load
