Performance Tuning for High Throughput Writes in MongoDB

Use unordered batch writes (bulkWritewithordered:false) to improve write efficiency; 2. If the risk of data loss is acceptable, disable logs (j:false or global shutdown journal) to reduce I/O overhead; 3. Tune the WiredTiger storage engine to increase cache, enable compression and pre-slice to avoid hotspots; 4. Simplify the indexing strategy, create only necessary indexes to avoid excessive indexes to slow down writes; 5. Realize horizontal scaling through hash sharding, and distribute the write load to support high throughput. The core of optimization lies in batch processing, reducing persistence requirements, rationally configuring storage, controlling the number of indexes and timely sharding, thereby maximizing MongoDB write performance and ultimately achieving stable and efficient write-intensive w

How to Implement a Search Autocomplete Feature in MongoDB

Use regular expressions, prefix indexes, or MongoDBAtlasSearch to achieve automatic completion of MongoDB search: create indexes for fields and use $regex to achieve basic prefix matching, or pre-generate prefix arrays and create multi-key indexes to improve performance, or use the built-in autocomplete analyzer in Atlas to achieve efficient real-time suggestions.

How to Use Transactions in MongoDB

MongoDB supports multi-document transactions since version 4.0 and needs to be used in replica sets or sharded cluster environments; when using it, transactions must be started through a session, operations must be performed and submissions or rollbacks are properly handled. At the same time, transactions should be kept short, high concurrency scenarios should be avoided, and command restrictions and timeout control should be paid attention to.

How to Secure Your MongoDB Database

Enabling authentication, restricting network access, enabling encryption and keeping updates are the core measures to protect MongoDB. First, enable authentication and use a strong password to create a user with minimal permission; secondly, restrict access through bindIp and firewall to avoid exposure to the public network; then enable TLS/SSL encryption to transmit data, and encrypt data at rest in combination with file system or MongoDB native functions; finally update the version regularly, enable audit logs and monitor abnormal behaviors to ensure database security.
