Packfile is an efficient mechanism used by Git to package, compress and transfer repository objects. When you execute gitpush, gitfetch or gitclone, what Git actually transmits is the packfile; 1. It is initially generated by loose objects through gitgc or gitrepack commands and stored in the .git/objects/pack/ directory; 2. The packfile not only contains object data, but also records the delta relationship between objects, and achieves rapid search with index file (.idx). 3. This design reduces the transmission volume and improves synchronization efficiency; 4. A large number of small packfiles may affect performance, and can be used through gitgc or git

MySQL supports transaction processing, and uses the InnoDB storage engine to ensure data consistency and integrity. 1. Transactions are a set of SQL operations, either all succeed or all fail to roll back; 2. ACID attributes include atomicity, consistency, isolation and persistence; 3. The statements that manually control transactions are STARTTRANSACTION, COMMIT and ROLLBACK; 4. The four isolation levels include read not committed, read submitted, repeatable read and serialization; 5. Use transactions correctly to avoid long-term operation, turn off automatic commits, and reasonably handle locks and exceptions. Through these mechanisms, MySQL can achieve high reliability and concurrent control.

Character set and sorting rules issues are common when cross-platform migration or multi-person development, resulting in garbled code or inconsistent query. There are three core solutions: First, check and unify the character set of database, table, and fields to utf8mb4, view through SHOWCREATEDATABASE/TABLE, and modify it with ALTER statement; second, specify the utf8mb4 character set when the client connects, and set it in connection parameters or execute SETNAMES; third, select the sorting rules reasonably, and recommend using utf8mb4_unicode_ci to ensure the accuracy of comparison and sorting, and specify or modify it through ALTER when building the library and table.
