Answer
Read concern determines the consistency level of reads, such as local, majority, or snapshot for transactions.
Quick Answer
Read concern controls data freshness and isolation for read operations. local: returns data that may not be majority-committed (default). majority: returns data acknowledged by majority of replicas - won't roll back. linearizable: guarantees reading the most recent majority-committed data (slowest). snapshot: consistent point-in-time view for transactions. Choose based on consistency requirements.
