travamento de leitura
1. A synchronization mechanism in concurrent programming that allows multiple threads or processes to simultaneously read shared data while preventing write operations
The database uses a read lock to ensure that multiple users can access the same record at the same time without conflicts.
O banco de dados usa um travamento de leitura para garantir que múltiplos usuários possam acessar o mesmo registro simultaneamente sem conflitos.
2. A lock that permits concurrent read access but blocks write access until all read locks are released
When a read lock is acquired, other threads can also obtain read locks, but no thread can acquire a write lock.
Quando um travamento de leitura é adquirido, outras threads também podem obter travamentos de leitura, mas nenhuma thread pode adquirir um travamento de escrita.
Read lock is a technical term primarily used in software engineering and database management contexts. It is consistently used across English and Portuguese-speaking technical communities, though Brazilian Portuguese typically translates it as 'travamento de leitura' while European Portuguese may prefer 'bloqueio de leitura'. In many technical settings, especially in code documentation and discussions, the English term 'read lock' is retained even in Portuguese texts.
