Spring Boot 3.5.3 MongoDB connection pool properties spring.data.mongodb max-pool-size socket-timeout

💡 Result:

In Spring Boot 3.5.x, Spring Boot’s spring.data.mongodb.* properties do not include dedicated “pool” or “socket timeout” fields (Boot mainly exposes spring.data.mongodb.uri, etc.). (docs.spring.io)
So, to set max pool size and socket timeout, use one of these approaches:

1) Put driver options on spring.data.mongodb.uri (recommended for simple config)

MongoDB Java driver supports these URI options:

  • Pool size: maxPoolSize (and minPoolSize)
  • Timeouts: connectTimeoutMS, socketTimeoutMS (note: socketTimeoutMS is deprecated in newer driver docs in favor of client-level timeout) (mongodb.com)

Example (application.yml):

spring:
  data:
    mongodb:
      uri: mongodb://user:pass@host:27017/mydb?maxPoolSize=50&connectTimeoutMS=10000&socketTimeoutMS=15000

Defaults worth knowing: maxPoolSize defaults to 100 if not set. (mongodb.ac.cn)

2) Customize MongoClientSettings (best if you want “typed” config / advanced tuning)

Spring Boot builds the client using MongoClientSettings, and the MongoDB driver lets you set pool and socket settings there (e.g., socket read timeout). (mongodb.com)

🌐 Web query:

Spring Data MongoDB connection pool configuration spring.data.mongodb.uri options replicaSet maxPoolSize socketTimeoutMS

💡 Result:

In Spring Boot / Spring Data MongoDB you can pass MongoDB driver connection-string options directly via spring.data.mongodb.uri, and Spring Boot will apply them when it auto-configures MongoClientSettings. (docs.spring.io)

1) Configure via spring.data.mongodb.uri (replicaSet, pool, timeouts)

Example:

spring.data.mongodb.uri=mongodb://user:pass@host1:27017,host2:27017,host3:27017/mydb\
?replicaSet=rs0\
&maxPoolSize=200\
&minPoolSize=10\
&socketTimeoutMS=45000\
&connectTimeoutMS=10000

Relevant URI options (driver-level):

  • replicaSet (replica set name) (mongodb.com)
  • maxPoolSize / minPoolSize (connection pool sizing; maxPoolSize default is 100) (mongodb.com)
  • socketTimeoutMS (socket read/write timeout; docs note default “never timeout”, driver-dependent) (mongodb.com)
  • connectTimeoutMS (connect timeout) (mongodb.com)

Note: in the Java driver, pool sizing applies per server in the topology. (mongodb.com)

2) When URI options aren’t enough: customize MongoClientSettings

Spring Boot supports MongoClientSettingsBuilderCustomizer to fine-tune MongoClientSettings. (docs.spring.io)

Spring Boot 3.5.3에서는 지정한 MongoDB 풀/타임아웃 속성들이 지원되지 않습니다.

현재 설정의 max-pool-size, min-pool-size, max-wait-time, socket-timeout, connect-timeout, max-connection-idle-time은 Spring Boot 3.5.3에서 인식되지 않는 속성으로, 이들은 무시되고 PR의 목적(커넥션 풀 조정)이 전혀 반영되지 않습니다.

다음 중 하나의 방법으로 수정하세요:

  1. spring.data.mongodb.uri를 사용 (권장):

    spring:
  data:
    mongodb:
      uri: mongodb://${MONGO_USERNAME}:${MONGO_PASSWORD}@${MONGO_HOST}:${MONGO_PORT}/${MONGO_DATABASE}?authSource=${MONGO_AUTH_DATABASE}&maxPoolSize=30&minPoolSize=10&connectTimeoutMS=1000&socketTimeoutMS=3000

  2. MongoClientSettingsBuilderCustomizer 빈 생성: 더 복잡한 설정이 필요한 경우 커스텀 빈을 작성하여 MongoClientSettings를 직접 구성합니다.

In `@backend/src/main/resources/application-prod.yml` around lines 19 - 26, The
YAML uses unsupported MongoDB pool/timeout properties (max-pool-size,
min-pool-size, max-wait-time, socket-timeout, connect-timeout,
max-connection-idle-time) for Spring Boot 3.5.3 so replace them by either
setting connection options in the Mongo URI via spring.data.mongodb.uri (include
maxPoolSize, minPoolSize, connectTimeoutMS, socketTimeoutMS, authSource as query
params) or implement a MongoClientSettingsBuilderCustomizer bean to
programmatically set MongoClientSettings (configure connectionPoolSettings and
socketSettings/connectTimeouts) so the pool/timeouts take effect.
