Hudi Spark SQL Call Procedures学习总结（一）（查询统计表文件信息）

前言

学习总结Hudi Spark SQL Call Procedures，Call Procedures在官网被称作存储过程（Stored Procedures），它是在Hudi 0.11.0版本由腾讯的

ForwardXu

大佬贡献的，它除了官网提到的几个Procedures外，还支持其他许多Procedures命令。本文先学习其中的几个我觉得比较常用的命令，主要是查询统计表路径下的各种文件信息。

版本

Hudi master 0.13.0-SNAPSHOT
Spark 3.1.2 (实际上所有Hudi支持的Spark版本都支持Call Procedures)
Kyuubi 1.5.2 (使用Kyuubi是因为返回结果可以展示列名，Spark自带的spark-sql不返回列名)

参数形式

按名称传递参数，没有顺序，可以省略可选参数

CALL system.procedure_name(arg_name_2 => arg_2, arg_name_1 => arg_1,... arg_name_n => arg_n)

按位置参数传递参数，有顺序，可以省略可选参数

CALL system.procedure_name(arg_1, arg_2,... arg_n)

支持的Procedures命令

我们可以在类

HoodieProcedures

获取对应版本支持的所有的Procedures命令。目前支持如下：

show_fs_path_detail

show_table_properties

查看表的properties,以key,value的形式返回

hoodie.properties

中表的配置

参数

  • table 表名
  • path 表路径
  • limit 可选 默认值10 table和path两个参数必须得有一个，table的优先级高于path,即如果同时指定table和path，那么以table为准，path不生效。 输出返回字段： key,value

示例

call show_table_properties(table=>'test_hudi_call_cow');call show_table_properties(path =>'hdfs://cluster1/warehouse/tablespace/managed/hive/hudi.db/test_hudi_call_cow');

show_commits_metadata

和show_commits功能差不多，不同的是输出字段不一样，和show_commits一样都是通过ShowCommitsProcedures实现的，区别是show_commits_metadata的includeExtraMetadata为true,show_commits的includeExtraMetadata为false

参数

  • table 表名 必选
  • limit 默认值10 可选 输出返回字段： commit_time,action,partition,file_id,previous_commit,num_writes,num_inserts,num_deletes,num_update_writes,total_errors,total_log_blocks,total_corrupt_log_blocks,total_rollback_blocks,total_log_records, total_updated_records_compacted,total_bytes_written

show_commit_files

根据instantTime返回对应的文件信息，比如fileId

参数

  • table 表名 必选
  • instant_time 必选
  • limit 默认10 可选 输出返回字段： action,partition_path,file_id,previous_commit,total_records_updated,total_records_written,total_bytes_written,total_errors,file_size

示例

call show_commit_files(table=>'test_hudi_call_cow', instant_time =>'20221123205701931');

因为测试数据比较少件，且只有一个分区，，所以只有一个文件

+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+|action| partition_path  |                 file_id                 |  previous_commit   | total_records_updated  | total_records_written  | total_bytes_written  | total_errors  | file_size  |+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+|commit| dt=2021-05-05|35b07424-6e63-4b65-9182-7c37cbe756b1-0|20221123205650038|0|4|435308|0|435308|+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+

执行下面的sql，使一次commit涉及两个文件

mergeinto test_hudi_call_cow as t0
using(select5as id,'hudi'as name,112as price,98as ts,'2022-11-23'as dt,'INSERT'as opt_type unionselect2as id,'hudi_2'as name,10as price,100as ts,'2021-05-05'as dt,'UPDATE'as opt_type unionselect4as id,'hudi'as name,10as price,100as ts,'2021-05-05'as dt ,'DELETE'as opt_type
 )as s0
on t0.id = s0.id
whenmatchedand opt_type!='DELETE'thenupdateset*whenmatchedand opt_type='DELETE'thendeletewhennotmatchedand opt_type!='DELETE'theninsert*;

先用show_commits查看最新的commit_time为20221123232449644

call show_commits(table=>'test_hudi_call_cow',limit=>1);+--------------------+---------+----------------------+--------------------+----------------------+---------------------------+------------------------+-------------------------------+---------------+|    commit_time     |action| total_bytes_written  | total_files_added  | total_files_updated  | total_partitions_written  | total_records_written  | total_update_records_written  | total_errors  |+--------------------+---------+----------------------+--------------------+----------------------+---------------------------+------------------------+-------------------------------+---------------+|20221123232449644|commit|870474|1|1|2|4|1|0|+--------------------+---------+----------------------+--------------------+----------------------+---------------------------+------------------------+-------------------------------+---------------+

然后再用show_commit_files看一下20221123232449644对应的文件

call show_commit_files(table=>'test_hudi_call_cow', instant_time =>'20221123232449644');+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+|action| partition_path  |                 file_id                 |  previous_commit   | total_records_updated  | total_records_written  | total_bytes_written  | total_errors  | file_size  |+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+|commit| dt=2022-11-23|8f2aecfd-198f-405b-ab5d-46e0cc997d97-0|null|0|1|435176|0|435176||commit| dt=2021-05-05|35b07424-6e63-4b65-9182-7c37cbe756b1-0|20221123231230786|1|3|435298|0|435298|+---------+-----------------+-----------------------------------------+--------------------+------------------------+------------------------+----------------------+---------------+------------+

show_commit_partitions

根据instantTime返回涉及的每个分区对应的文件和记录信息

参数

  • table 表名 必选
  • instant_time 必选
  • limit 默认10 可选 输出返回字段： action,partition_path,total_files_added,total_files_updated,total_records_inserted,total_records_updated,total_bytes_written,total_errors

示例

call show_commit_partitions(table=>'test_hudi_call_cow', instant_time =>'20221123232449644');

+---------+-----------------+--------------------+----------------------+-------------------------+------------------------+----------------------+---------------+|action| partition_path  | total_files_added  | total_files_updated  | total_records_inserted  | total_records_updated  | total_bytes_written  | total_errors  |+---------+-----------------+--------------------+----------------------+-------------------------+------------------------+----------------------+---------------+|commit| dt=2022-11-23|1|0|1|0|435176|0||commit| dt=2021-05-05|0|1|0|1|435298|0|+---------+-----------------+--------------------+----------------------+-------------------------+------------------------+----------------------+---------------+

show_commit_write_stats

根据instantTime返回write_stats

参数：

  • table 表名 必选
  • instant_time 必选
  • limit 默认10 可选 输出返回字段： action,total_bytes_written,total_records_written,avg_record_size

示例

call show_commit_write_stats(table=>'test_hudi_call_cow', instant_time =>'20221123232449644');

+---------+----------------------+------------------------+------------------+|action| total_bytes_written  | total_records_written  | avg_record_size  |+---------+----------------------+------------------------+------------------+|commit|870474|4|217619|+---------+----------------------+------------------------+------------------+

show_commit_extra_metadata

参数

  • table 表名 必选
  • instant_time 可选
  • limit 默认100 可选
  • metadata_key 可选 如schema 输出返回字段： instant_time,action,metadata_key,metadata_value

先看一下.commit里的内容，可以看到里面有一个extraMetadata,并且包含一个key:schema以及schema对应的value

我目前已知的extraMetadata中只有schema，且只有一条，所以只返回一条记录，且指定不指定metadata_key效果一样，不确定是否还有其他的extraMetadata

show_fs_path_detail

展示指定路径下面的文件和路径的统计信息，默认按照文件大小进行排序
返回.commit、.deltacommit、.replacecommit中的extraMetadata
