Table compression is also not available for the InnoDB system tablespace. The system tablespace (space 0, the ibdata* files) can contain user data, but it also contains internal system information, and therefore is never compressed. Thus, compression applies only to tables (and indexes) stored ...
• When creating a compressed table in a file-per-table tablespace, setting KEY_BLOCK_SIZE equal to the InnoDB page size does not typically result in much compression. For example, setting KEY_BLOCK_SIZE=16 typically would not result in much compression, since the normal InnoDB page size is...

For example, settingKEY_BLOCK_SIZE=16typically would not result in much compression, since the normalInnoDBpage size is 16KB. This settin...
17.9.1.1 Overview of Table Compression Because processors and cache memories have increased in speed more than disk storage devices, many workloads aredisk-bound. Datacompressionenables smaller database size, reduced I/O, and improved throughput, at the small cost of increased CPU utilization. Compre...
myisam table compressionPosted by: Jacky Shu Date: January 09, 2006 01:01PM Scenario: Huge myisam log table needs compression for maintenance. This table is replicated to several databases. Question: Is there any way that I can compress this table on the master db and it is ...

There is usually a different Huffman table for each column. Suffix space compression. Prefix space compression. Numbers with value 0 are stored using 1 bit. If values in an integer column have a small range, the column is stored using the smallest possible type. For example, a BIGINT column...
bytes. To determine a validKEY_BLOCK_SIZEvalue for a givenFILE_BLOCK_SIZE, divide theFILE_BLOCK_SIZEvalue by 1024. Table compression is not support for 32K and 64KInnoDBpage sizes. For more information aboutKEY_BLOCK_SIZE, seeCREATE TABLE, andSection 15.9.1.2, “Creating Compressed Tables”....
