Mysql DB 용량 확인

스키마별 용량 확인

SELECT count(*) NUM_OF_TABLE,
		table_schema,concat(round(sum(table_rows)/1000000,2),'M') rows,
		concat(round(sum(data_length)/(1024*1024*1024),2),'G') DATA,
		concat(round(sum(index_length)/(1024*1024*1024),2),'G') idx,
		concat(round(sum(data_length+index_length)/(1024*1024*1024),2),'G') total_size,
		round(sum(index_length)/sum(data_length),2) idxfrac
 FROM information_schema.TABLES
GROUP BY table_schema
ORDER BY sum(data_length+index_length) DESC;

           

특정 스키마 용량 확인

 SELECT table_name,
		table_rows,
		round(data_length/(1024*1024),2) as 'DATA_SIZE(MB)',
		round(index_length/(1024*1024),2) as 'INDEX_SIZE(MB)'
 FROM information_schema.TABLES 
 WHERE table_schema = ${db_name}
 GROUP BY table_name 
 ORDER BY data_length DESC;
