Description

Add the query coordinator loop, following the compression coordinator’s structure and using #2513’s QueryJobHandle interface.

  • Poll pending query jobs, decode their MessagePack configuration, and dispatch searches under a concurrency limit.
  • Recover running jobs using their persisted Spider job IDs.
  • Pass SearchJobConfig and OutputHandle to the handler.
  • Add coordinator configuration, resource-group initialization, shutdown signaling, and the query table’s dispatch_time column.

Depends on #2513 and uses #2512’s output-handle definitions.

Summary by CodeRabbit

  • New Features

    • Added query-job coordination to discover, submit, monitor, recover, and update CLP search jobs.
    • Added single-archive CLP search tasks with support for query options, time ranges, result limits, and case-insensitive matching.
    • Added results-cache output handling and archive object-key generation.
    • Added query job status tracking, dispatch metadata, and resource-group coordination.
  • Documentation

    • Documented the new query task and updated task package documentation.

… search results to the results cache.

Implements `query::clp_s_query_to_results_cache`, mirroring the Celery task in
`job_orchestration.executor.query.fs_search_task`. The task resolves one archive from either
filesystem- or S3-backed archive output, invokes `clp-s s`, and lets `clp-s` write the matches to
MongoDB itself. Aggregation and the file/network/reducer output handlers are not supported.

* Add `OutputHandle` to `task_io::query` and make `ClpSQueryOption::max_num_results` optional, so
  `None` means no task-level limit rather than silently inheriting the `clp-s` default of 1000.
  Correct the `begin_timestamp`/`end_timestamp` doc comments, which said microseconds; the whole
  chain is milliseconds.
* Add `ArchiveOutput::dataset_archive_object_key`, and move `clp_binary_path` and
  `s3_credential_env` out of the compression task into `task::clp_s`, so the compression and query
  paths share one definition of the archive layout and of the AWS credential environment.
* Resolve a `None` dataset to `default` on the Rust side and always pass `--dataset`, so every
  result document carries a truthful dataset name instead of an empty string.
* Pass the query job ID into `build_clp_s_search_args_for_result_cache` and derive the
  results-cache collection name inside it.
* Rename `build_clp_s_search_args` to `build_clp_s_search_args_for_result_cache`.
* Log an error when archive-input resolution fails.
* Tighten the task's docstrings and error messages.
…`clp-s` search task:

* Rename the `build_clp_s_search_args_for_result_cache` unit tests to match the function's name.
* Rename `results_cache_uri` to `result_cache_uri`.

dispatch_time, and the JOB_SPIDER_ID index, ignoring duplicate-column and
duplicate-index errors while re-raising other failures; import ER_DUP_FIELDNAME
alongside ER_DUP_KEYNAME.

In `@components/clp-rust-utils/src/clp_config/package/config.rs`:
- Around line 509-514: Update the Config struct to add a public optional

None in Config’s Default implementation so package YAML deserialization
preserves configured coordinator values.
- Around line 287-291: Extend the shared ResultsCache configuration with a
configurable TLS option, preserving plaintext as the default for local and
bundled deployments. Update ResultsCache::uri to emit the appropriate MongoDB
URI scheme based on that option, and propagate the same setting to the

- Around line 154-164: Validate the URL produced by generate_s3_url before
calling s3_credential_env or using it for S3 access, rejecting credentialed HTTP
endpoints by default. Permit HTTP only when an existing explicit restricted
insecure-development configuration enables it, while preserving HTTPS behavior
and returning a clear configuration error for disallowed schemes.

In `@components/clp-tdl-package/src/task/utils.rs`:
- Around line 82-84: Update the command setup in run_clp_s_search, compression
run_clp_s, and run_log_converter to call env_remove("AWS_SESSION_TOKEN") before

an executable launcher that loads QueryCoordinator, constructs Coordinator::new,

- Around line 250-253: Guard the mark_job_failed update on the job’s expected
prior status, matching the transition checks in job_handle.rs, so it cannot

expected QueryJobStatus and include it in the UPDATE predicate; pass Pending
from schedule_new_jobs and create_job_handle, and Running from
fetch_submitted_running_jobs.
- Line 239: Update Coordinator::run so recoverable database errors from
schedule_new_jobs and mark_jobs_dispatched are logged and retried without

mark_jobs_dispatched before fetching additional Pending rows, preventing
duplicate detached handles; retain normal polling after successful recovery.

In `@components/query-coordinator/src/job_handle.rs`:
- Line 228: Implement QueryJobHandle::prepare_task_inputs and replace the todo
panic with a fallible result; when planning is unavailable, return an Error so
QueryJobHandle::run can call report_failure and persist the job as Failed before
dispatch.
- Around line 347-352: Truncate the message bound as status_msg in the query
update to the VARCHAR(512) column width before executing it. Apply the same
truncation behavior used by coordination.rs, including for the prefixed error
produced by to_completion, while preserving the existing default for absent
messages.

Add a migration for existing query_jobs tables.

CREATE TABLE IF NOT EXISTS does not alter an existing table. On an upgraded deployment, query_jobs keeps the old schema and lacks status_msg, spider_id, and dispatch_time. Every coordinator statement that references those columns then fails with an unknown-column error: coordination.rs lines 250-253, 364-368, 448-457, and 525-529, plus job_handle.rs lines 244-247 and 347-350. The query coordinator cannot dispatch or finalize any job.

Add an idempotent ALTER TABLE migration, following the existing JOB_START_TIME_STATUS pattern at lines 92-105.

🐛 Proposed migration
             scheduling_db_cursor.execute(
                 f"""
                 CREATE TABLE IF NOT EXISTS `{QUERY_TASKS_TABLE_NAME}` (

Insert before the QUERY_TASKS_TABLE_NAME statement:

            # Add columns and index to existing tables that were created before
            # they were added to the CREATE TABLE statement. Ignoring duplicate
            # errors makes this idempotent for databases that already have them.
            for alteration in (
                "ADD COLUMN `status_msg` VARCHAR(512) NOT NULL DEFAULT ''",
                "ADD COLUMN `spider_id` BIGINT UNSIGNED NULL DEFAULT NULL",
                "ADD COLUMN `dispatch_time` DATETIME NULL DEFAULT NULL",
                "ADD INDEX `JOB_SPIDER_ID` (`spider_id`) USING BTREE",
            ):
                try:
                    scheduling_db_cursor.execute(
                        f"ALTER TABLE `{QUERY_JOBS_TABLE_NAME}` {alteration}"
                    )
                except Exception as err:

Security Misconfiguration

Reachability: Internal
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Make TLS configurable for remote result-cache connections.

ResultsCache.host supports non-bundled deployments, so it can point to a remote MongoDB server. ResultsCache::uri() always emits a plaintext mongodb:// URI, and the coordinator consumes it directly. The analogous Python consumers use the same plaintext URI format.

Do not force TLS for every deployment because the defaults support local and bundled plaintext MongoDB. Add a configurable TLS option to the shared result-cache configuration and apply the resulting URI consistently to the coordinator and other consumers.

Expose QueryCoordinator in Config. Config has no query_coordinator field, and the repository has no direct deserialization entry point for QueryCoordinator. A package YAML value is therefore ignored when deserialized as Config, so the coordinator cannot receive its configured values. Add pub query_coordinator: Option<QueryCoordinator> and initialize it to None in Default.

Remove inherited AWS_SESSION_TOKEN values before applying credentials.

When session_token is None, s3_credential_env returns only the access key and secret key. run_clp_s_search, compression run_clp_s, and run_log_converter pass that list to std::process::Command::envs, which leaves inherited variables unchanged. A child process can therefore send a stale token with the selected credentials and fail S3 authentication.

Call .env_remove("AWS_SESSION_TOKEN") before .envs(...) in each command. This still allows .envs(...) to set the selected token when one exists.

Wire the query coordinator into a runnable service. components/query-coordinator/Cargo.toml declares no executable target, and no caller invokes Coordinator::new or Coordinator::run. The package image and service manifests wire only the compression coordinator. The API can create PENDING rows in query_jobs, but this Spider-backed coordinator cannot process them because its runtime path is unreachable. The existing query scheduler is a separate implementation.

Add an executable, launcher, and package/service wiring that loads QueryCoordinator, constructs Coordinator::new, and calls run, following the compression coordinator pattern. Exposing configuration alone does not invoke the coordinator.

Keep the poll loop running after recoverable database errors.

Coordinator::run propagates failures from schedule_new_jobs and mark_jobs_dispatched with ?. A transient database error therefore returns from run, and that coordinator instance performs no further polls. Detached handles that were already spawned can continue.

Log recoverable errors and retry. Preserve the IDs from the affected dispatch attempt and retry mark_jobs_dispatched before fetching more Pending rows. A fresh fetch can select a still-Pending row with a NULL dispatch_time and spawn a duplicate detached handle.

Guard mark_job_failed on the expected prior status.

The UPDATE keys on id only. The coordinator reads the row in fetch_new_job_rows or fetch_submitted_running_jobs and updates it later. If a user cancels the job in that window, this statement overwrites Cancelled with Failed, and the user sees a failure instead of the cancellation.

job_handle.rs already guards every transition on the observed status. Apply the same guard here.

Do not dispatch search jobs until prepare_task_inputs is implemented.

Coordinator::schedule_new_jobs creates a detached QueryJobHandle for each eligible non-aggregation search job. QueryJobHandle::run then reaches prepare_task_inputs and panics before submission. The panic bypasses report_failure, so the row remains Pending with spider_id set to NULL. The later dispatch update normally sets dispatch_time but does not change the status.

Subsequent polls do not select that row because they require dispatch_time IS NULL. A coordinator restart can select it through FIRST_FETCH_QUERY, which selects pending rows with a non-null dispatch_time, and the job panics again. Running-job recovery does not select it because the row is not Running and has no spider_id.

Implement prepare_task_inputs. If planning is not ready, return an Error instead of panicking so run can persist the job as Failed.

official MariaDB 10.11 documentation strict mode default data too long VARCHAR assignment

💡 Result:

<search_synthesis>
In MariaDB 10.11, strict mode is enabled by default [1][2]. When strict mode is active, attempting to assign data to a VARCHAR column that exceeds its defined length results in an error, specifically ERROR 1406 (22001): Data too long for column [3][4]. Under this configuration: 1. Strict mode is defined as having at least one of the sql_mode flags STRICT_TRANS_TABLES or STRICT_ALL_TABLES enabled [1][5]. 2. Because strict mode is the default (as it has been since MariaDB 10.2.4), statements that modify tables will fail when attempting to insert or update data that is too long, rather than silently truncating the data [1][3]. 3. If you wish to allow truncation and convert this error into a warning, you can use the IGNORE keyword in your SQL statement, which suppresses the error even when strict mode is active [1][5]. For verification, you can check your current session&#39;s mode by executing SELECT @@sql_mode [5].

Because it was published a while ago, some of the information, links, or context may now be outdated. Let us take a closer look at MariaDB strict mode and how to enable it in a few simple steps. Bobcares answers all your questions on MariaDB as part of our Server Management Services ### MariaDB The Mariadb has numerous modes including the strict mode that allows users to adapt it to their specific needs. The most essential methods are to use SQL MODE (controlled by the sql mode system variable) and OLD MODE (controlled by the old mode system variable). SQL MODE instructs MariaDB to replicate the behavior of other SQL servers, whereas OLD MODE instructs MariaDB to emulate the behavior of older MariaDB or MySQL versions. SQL MODE is a string with options separated by commas (‘,’) and no spaces. The choices are not case-sensitiveCheck it’s local and worldwide worth with: ``` SELECT @@SQL_MODE, @@GLOBAL.SQL_MODE; ``` #### Strict All Tables MariaDB Strict mode; statements that include invalid or missing data are in rollback. For use with a non-transactional storage engine and a statement that affects several rows. This means a partial insert or update if the error is found in a row beyond the first. #### Strict Trans Tables Except for non-transactional storage engines and statements impacting many rows where the invalid or missing data is not the initial row. The statement containing invalid or missing data set in abort and rollback state. MariaDB will either convert the invalid value to the nearest valid value or insert the column default value if a value is absent. MariaDB 10.2.4 is the default. ### Strict Mode The Mariadb Strict mode is one that has at least one of STRICT TRANS TABLES or STRICT ALL TABLES enabled. After setting the strict mode, statements that edit tables fail, and an exception will return. When strict mode is enabled, the IGNORE keyword can be used to turn an error into a warning. After the initiation of the strict mode, MariaDB will automatically adjust invalid values, such as truncating strings that are too lengthy or altering numeric values that are out of range, and will generate a warning. When adjusted, statements that do not affect data will return a warning regardless of mode. ### sql mode – Get and Set sql mode (Strict Mode) Settings in MySQL In the case of MariaDB, strict mode MySQL SQL mode specifies the SQL syntax that is supported, and MySQL performs data validation. ``` Syntax: SET [GLOBAL|SESSION] sql_mode=&`#39`;mode1,mode2, …&`#39`; ``` ``` Quick Example: SET sql_mode = &`#39`;ANSI_QUOTES,PIPES_AS_CONCAT&`#39`;; ``` ``` Strict Mode: When STRICT_TRANS_TABLES or STRICT_ALL_TABLES is specified ``` ``` MySQL Configuration: The user can set sql_mode in my.cnf (Unix), my.ini (Windows), or --sql-mode ``` (command line) ### Get and Set sql_mode Getting the current sql mode value for finalizing the configurations on mariadb strict mode. Get the current value, which may have previously been modified by the SET SQL mode statement, executed in the current session SELECT @@sql_mode; Obtain the global value, which is unaffected by SET sql mode. SELECT @@GLOBAL.sql_mode; Modify the current sql mode: ``` SET sql_mode=&`#39`;STRICT_TRANS_TABLES,ANSI_QUOTES&`#39`;; ``` This is the final step in setting up the MariaDB strict mode. #### Conclusion To conclude, it is easy to enable the Mariadb strict mode. Statements that alter tables will fail when strict mode is enabled, and an error will be returned in their place. inquiry@bobcares.com | 1-800-383-5193 (18003835193)

Truncate status_msg to the column width.

When Spider reports JobState::Failed, get_job_error supplies an unbounded String. to_completion adds a prefix and passes the result directly to status_msg VARCHAR(512).

When the database connection uses strict SQL mode, the over-length UPDATE fails instead of truncating the value. This is the default for the packaged MariaDB 10.11 deployment. to_completion then returns an error, so the query job remains Running; recovery can retry the same failing update. Non-strict mode truncates the value and does not expose this failure.

Use the same truncation applied by coordination.rs:

🐛 Proposed fix
         let query = sqlx::query(formatcp!(
-            "UPDATE `{QUERY_JOBS_TABLE_NAME}` SET `status` = ?, `status_msg` = ? WHERE `id` = ? \
-             AND `status` = ?"
+            "UPDATE `{QUERY_JOBS_TABLE_NAME}` SET `status` = ?, `status_msg` = LEFT(?, 512) \
+             WHERE `id` = ? AND `status` = ?"
         ))

Truncate the message bound as status_msg in the query update to the VARCHAR(512)
column width before executing it. Apply the same truncation behavior used by
coordination.rs, including for the prefixed error produced by to_completion,
while preserving the existing default for absent messages.
