Read test query results before reporting JDBC container as ready by seonwooj0810 · Pull Request #12090 · testcontainers/testcontainers-java

seonwooj0810 · 2026-09-24T14:17:48Z

JdbcDatabaseContainer#waitUntilContainerStarted treated the container as ready as soon as Statement#execute(testQuery) returned true. That only means the query produced a result set. It does not mean the results can actually be read. As @szymonm found in the issue thread, Trino accepts SELECT count(*) FROM tpch.tiny.nation during startup, and the query then fails with No nodes available to run query once the results are fetched. The container is reported ready anyway, and the first user query fails.

This change reads the test query's result set to the end before returning. If fetching the results fails, the exception goes to the existing retry path and the query is tried again until it succeeds or the startup timeout is reached. The built-in test queries are constant or trivially small SELECTs (SELECT 1, SELECT 1 FROM DUAL, OrientDB's SELECT FROM V on a fresh database, ...), so reading their results costs essentially nothing for the other databases. The fix is in the shared JdbcDatabaseContainer, so it covers both TrinoContainer classes (and PrestoContainer, which has the same structure) without copying the retry loop into each module.

Tests

Added JdbcDatabaseContainerTest#testQueryIsRetriedIfReadingItsResultsFails. It uses a stubbed connection where execute succeeds but ResultSet#next() throws on the first attempt, and it asserts that the readiness check retries (2 connection attempts). It fails on main (Expecting AtomicInteger(1) to have value: 2) and passes with this change. It needs no Docker and is deterministic, unlike the Trino startup race.

Verification done:

./gradlew :testcontainers-jdbc:test: all tests pass
./gradlew :testcontainers-trino:test :testcontainers-postgresql:test against real containers: 4/4 and 34/34 pass
spotlessApply, checkstyleMain, checkstyleTest on the jdbc module: clean

(I used an AI coding assistant while preparing this change; I reviewed and tested it myself.)

📝 Walkthrough

Walkthrough

JDBC container startup now drains the readiness query result before reporting success. A test verifies that a SQLException while reading results leads to another connection attempt.

Changes

JDBC container readiness

Layer / File(s)	Summary
Drain readiness query results `modules/jdbc/src/main/java/org/testcontainers/containers/JdbcDatabaseContainer.java`, `modules/jdbc/src/test/java/org/testcontainers/containers/JdbcDatabaseContainerTest.java`	Startup reads all rows from the readiness query result when it is non-null. The test makes the first result read throw `SQLException` and verifies that startup makes a second connection attempt.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 356f8

A slow readiness-result fetch can make a JDBC container take longer to start than its configured timeout allows. Address that timeout behavior before merging unless the overrun is explicitly accepted.

the remaining startup deadline instead of relying on the driver's transport
timeout; use driver-compatible query timeout or cancellation where supported,
and stop waiting once the configured startup deadline expires.

The protocol is a sequence of REST API calls to the coordinator of the Trino cluster. Following is a high-level overview: 1. Client submits SQL query text to the coordinator of the Trino cluster. 2. The coordinator starts processing the query. 3. The coordinator returns a result set and a URI `nextUri` on the coordinator. 4. The client receives the result set and initiates another request for more data from the URI `nextUri`. 5. The coordinator continues processing the query and returns further data with a new URI. 6. The client and coordinator continue with steps 4. and 5. until all result set data is returned to the client or the client stops requesting more data. 7. If the client fails to fetch the result set, the coordinator does not initiate further processing, fails the query, and returns a `USER_CANCELED` error. 8. The final response when the query is complete is `FINISHED`. The client protocol supports two modes. Configure the spooling protocol for optimal throughput for your clients. ## Spooling protocol# The spooling protocol uses an object storage location to store the data for retrieval by the client. The coordinator and all workers can write result set data to the storage in parallel. The coordinator only provides the URLs to all the individual data segments on the object storage to the cluster. The spooling protocol also allows compression of the data. Data on the object storage is automatically removed after download by the client. The spooling protocol has the following characteristics, compared to the direct protocol. - Provides higher throughput for data transfer, specifically for queries that return more data. - Results in faster query processing completion on the cluster, independent of the client retrieving all data, since data is read from the object storage. - Requires object storage and configuration on the Trino cluster. - Reduces CPU and I/O load on the coordinator. - Automatically falls back to the direct protocol for queries that don’t benefit from using the spooling protocol. - Requires newer client drivers or client applications that support the spooling protocol and actively request usage of the spooling protocol. - Clients must have access to the object storage. - Works with older client drivers and client applications by automatically falling back to the direct protocol if spooling protocol is not supported. ### Configuration# The following steps are necessary to configure support for the spooling protocol on a Trino cluster: - Configure the spooling protocol usage in Config properties using the Spooling protocol properties. - Choose a suitable object storage that is accessible to your Trino cluster and your clients. - Create a location in your object storage that is not shared with any object storage catalog or spooling for any other Trino clusters. - Configure the object storage in `etc/spooling-manager.properties` using the Spooling file system properties. Minimal configuration in Config properties: ``` protocol.spooling.enabled=true protocol.spooling.shared-secret-key=jxTKysfCBuMZtFqUf8UJDQ1w9ez8rynEJsJqgJf66u0= ``` Note The `protocol.spooling.shared-secret-key` property requires a 256-bit, base64-encoded secret key. Refer to Spooling protocol properties for further optional configuration. Suitable object storage systems for spooling are S3 and compatible systems, Azure Storage, and Google Cloud Storage. The object storage system must provide good connectivity for all cluster nodes as well as any clients. Activate the desired system with `fs.s3.enabled`, `fs.azure.enabled`, or `fs.gcs.enabled` in `etc/spooling-manager.properties` and configure further details using relevant properties from Spooling file system properties, S3 file system support, Azure Storage file system support, and Google Cloud Storage file system...</excerpt> </source> <source> <title>Trino client REST API — Trino 483 Documentation</title> <location>https://trino.io/docs/current/develop/client-protocol.html</location> <excerpt>The REST API allows clients to submit SQL queries to Trino and receive the results. Clients include the CLI, the JDBC driver, and others provided by the community. The preferred method to interact with Trino is to use these existing clients. This document provides details about the API for reference. It can also be used to implement your own client, if necessary. ... If the JSON document returned by the `POST` to `/v1/statement` does not contain a `nextUri` link, the query has completed, either successfully or unsuccessfully, and no additional requests need to be made. If the `nextUri` link is present in the document, there are more query results to be fetched. The client should loop executing a `GET` request to the `nextUri` returned in the `QueryResults` response object until `nextUri` is absent from the response. ... | Attribute | Description | | --- | --- | | `id` | The ID of the query. | | `nextUri` | If present, the URL to use for subsequent `GET` or `DELETE` requests.

The following properties can be used after adding the specific prefix to the property. For example, for OAuth 2.0 authentication, you can enable HTTP for interactions with the external OAuth 2.0 provider by adding the prefix`oauth2-jwk` to the`http-client.connect-timeout` property, and increasing the connection timeout to ten seconds by setting the value to`10`: ``` oauth2-jwk.http-client.connect-timeout=10s ``` The following prefixes are supported: `oauth2-jwk` for OAuth 2.0 authentication `jwk` for JWT authentication ## General properties# ### http-client.connect-timeout# Default value:`5s` Minimum value:`0ms` Timeout value for establishing the connection to the external service. ### http-client.max-connections# Default value:`200` Maximum connections allowed to the service. ### http-client.request-timeout# Default value:`5m` Minimum value:`0ms` Timeout value for the overall request. ## TLS and security properties# ### http-client.https.excluded-cipher# A comma-separated list of regexes for the names of cipher algorithms to exclude. ### http-client.https.included-cipher# A comma-separated list of regexes for the names of the cipher algorithms to use. ### http-client.https.hostname-verification# Default value:`true` Verify that the server hostname matches the server DNS name in the SubjectAlternativeName (SAN) field of the certificate. ### http-client.key-store-password# Password for the keystore. ### http-client.key-store-path# File path on the server to the keystore file. ### http-client.secure-random-algorithm# Set the secure random algorithm for the connection. The default varies by operating system. Algorithms are specified according to standard algorithm name documentation. Possible types include`NativePRNG`,`NativePRNGBlocking`,`NativePRNGNonBlocking`,`PKCS11`, and`SHA1PRNG`. ### http-client.trust-store-password# Password for the truststore. ### http-client.trust-store-path# File path on the server to the truststore file. ## Proxy properties# ### http-client.http-proxy# Host and port for an HTTP proxy with the format`example.net:8080`. ### http-client.http-proxy.secure# Default value:`false` Enable HTTPS for the proxy. ### http-client.socks-proxy# Host and port for a SOCKS proxy. ## Request logging# ### http-client.log.compression-enabled# Default value:`true` Enable log file compression.

**Do not rely on the driver timeout to enforce the startup timeout.**

waitUntilContainerStarted() checks the deadline only in the outer loop. ResultSet.next() can block until the driver's own transport timeout, which is independent of the remaining startupTimeoutSeconds. This prevents an infinite single read, but startup can still exceed its configured deadline.

Enforce the remaining startup deadline while draining the result set, using driver-compatible cancellation or timeout configuration where supported.
