László Bodor updated HIVE-27980:
--------------------------------
    Description: 
Presently Hive Iceberg supports Major compaction using HIVE ACID syntax below.
{code:java}
ALTER TABLE name COMPACT MAJOR [AND WAIT] {code}
Add support for OPTIMIZE TABLE syntax. Example:
{code:java}
OPTIMIZE TABLE name REWRITE DATA

---- future options support ---
[USING BIN_PACK]
[ ( { FILE_SIZE_THRESHOLD | MIN_INPUT_FILES } = <value> [, ... ] ) ]
WHERE category = 'c1' {code}
This syntax will be inline with Impala.

Also, OPTIMIZE command is not limited to compaction, but also supports other 
table maintenance operations.

  was:
目前,Hive Iceberg 支持使用下面的 HIVE ACID 语法进行 Major 压缩。
{code:java}
ALTER TABLE name COMPACT MAJOR [AND WAIT] {code}
添加对 OPTIMIZE TABLE 语法的支持。例:
{code:java}
OPTIMIZE TABLE name REWRITE DATA

----  future options support --- 
[USING BIN_PACK]
[ ( { FILE_SIZE_THRESHOLD | MIN_INPUT_FILES } = <value> [, ... ] ) ]
WHERE category = 'c1' {code}
此语法将与 Impala 内联。

此外,OPTIMIZE 命令不仅限于压缩,还支持其他表维护操作。
