Fulltext Index Study8：Resouce Consumption

标签：

一，查看Disk Consumption

1，通过SSMS查看Full-Text Index 的 Disk Consumption

在Storage-》Full Text Catalogs，选择某一个Catalog，点击属性，查看Catalog Size，就是位于Catalog中的属于fulltext的internal tables的总大小。

2，Population Schedule

通过Population Schedule tab，创建schedule和Job，按照schedule对fulltext index进行reorganize。

ALTER FULLTEXT CATALOG [fulltext_catalog_name] 
REORGANIZE;

3，查询每个Table的Fragments的size

--fragment 
SELECT 
   [table] = OBJECT_SCHEMA_NAME(table_id) + ‘.‘ + OBJECT_NAME(table_id), 
   logical_size_MB = CONVERT(DECIMAL(12,2), SUM(data_size/1024.0/1024))
FROM sys.fulltext_index_fragments
-- WHERE table_id = OBJECT_ID(‘dbo.specific_table_name‘)
GROUP BY table_id;

data_size：Logical size of the fragment in bytes.

二，在Fulltext Index Population时，查看memory consumption

参考《Fulltext Index Study6：Monitor Population》

通过sys.dm_fts_memory_buffers 查看memory buffers used by a full-text crawl，通过sys.dm_fts_memory_pools查看memory pools used by a full-text crawl.

--returns the total shared memory owned by the Microsoft Full-Text Gatherer component  
SELECT SUM(buffer_size * buffer_count)/1024 AS total_memory_KB 
FROM sys.dm_fts_memory_pools

参考doc：

sys.fulltext_index_fragments (Transact-SQL) 

sys.dm_fts_memory_pools (Transact-SQL)

sys.dm_fts_memory_buffers (Transact-SQL)
