What type to choose when creating a new data table in Navicat?

Navicat provides the following data table types: InnoDB: supports transactions and high concurrency. MyISAM: Non-transactional, but faster. MEMORY: Store data in memory, extremely fast. Merge: Distributes data across multiple sub-tables, suitable for massive data sets. BLACKHOLE: Discard all written data, used for testing or deleting data.

New data table type selection in Navicat

When creating a new data table, Navicat provides a variety of tables Types are available for you to choose, depending on the intended use of the table.

1. InnoDB

• The default and most common table type.
• Supports transactions, foreign keys and crash recovery.
• Provides row-level locking to ensure concurrency.

2. MyISAM

• A non-transactional table type, but faster than InnoDB.
• Does not support transactions or foreign keys.
• Provides table-level locking, which may cause conflicts.

3. MEMORY

• Store data in memory, very fast.
• Very useful for data that needs to be accessed quickly and does not require persistent storage.
• Data will be lost when the server is restarted.

4. Merge

• Distribute data across multiple subtables.
• Very useful for massive data sets and can improve performance.
• Partitioning is not supported.

5. BLACKHOLE

• A special table that discards all data written.
• Use for testing purposes or to delete unnecessary data.

Selection criteria

• Transactions and concurrency: If you need transaction support and high concurrency, choose InnoDB.
• Speed: If speed is the primary consideration, choose MyISAM or MEMORY.
• Memory Usage: Select MEMORY if the data will be used in memory.
• Data volume: If the data volume is large, consider using the Merge table.
• Special Purpose: For testing or deleting data, use the BLACKHOLE table.
