- Fix not giving the databaseName in the "ImpalaController.get10PublicationIdsTest()".
- Improve consistency in the "maxAttemptsPerRecord" value, among different threads. Also, reduce the value-increase by one.
- Check if the tableName string is empty, in the "mergeParquetFiles".
- Improve error-logging.
- Set some local variables to "final", optimizing code-execution by the JVM.
- Fix an NPE, when the "getTestUrls"-endpoint is called. It was thrown because of an absent per-thread initialization of some thread-local variables.
- Fix JdbcTemplate error when querying the "getFileLocationForHashQuery".
- Fix the "S3ObjectStore.isLocationInStore" check.
- Fix not catching/handling some exceptions.
- Fix/improve log-messages.
- Optimize the "getFileLocationForHashQuery" to return only the first row. In the latest change, without this optimization, the query-result would cause non-handling the same-hash cases, because of an exception.
- Optimize the "ImpalaConnector.databaseLock.lock()" positioning.
- Update the "getTestUrls" api-path.
- Optimize list-allocation.
- Re-add the info-message about the successful emptying of the S3-bucket.
- Code cleanup.
- Fix not updating the fileLocation with the s3Url for records which share the same full-text.
- Set only one delete-order for each assignments-batch-files, not one (or more, by mistake) per zip-batch.
- Set the HttpStatus to "204 - NO_CONTENT", when no assignments are available to be returned to the Worker.
- Fix not unlocking the "dataBaseLock" in case of a "dataBase-connection"-error, in "addWorkerReport()".
- Improve some log-messages.
- Change the log-level for the "S3-bucket already exists" message.
- Update Gradle.
- Optimize imports.
- Code cleanup.
- Improve reliability, by dropping the "current_assignment" table in case of an error, thus the next "getUrls"-request will not fail.
- Fix the "databaseLock" not being unlocked when the "addWorkerReport()" method returned early on some error-cases.
- Delete the "assignment"-data after inserting the related payloads and attempts in the database.
- Fix a bug, which caused multiple workers to get assigned the same batch-counter, while the assignment-tasks where different.
- Set a max-size limit to the amount of space the logs can use. Over that size, the older logs will be deleted.
- Show the error-message returned from the Worker, when a getFullTexts-request fails.
- Improve some log-messages.
- Update dependencies.
- Code cleanup.
- Optimize the "findAssignmentsQuery" by using an inner limit (larger than the outer).
- Save a ton of time from inserting the assignments into the database, by using a temporal table to hold the new assignments, in order for them to be easily accessible both from the Controller (which processes them and send them to the Worker) and the database itself, in order to "import" them into the "assignment"-table.
- Replace the "Date" with "Timestamp", in order to hold more detailed information.
- Code cleanup.
- Fix the "null" representation of an "unknown" payload-size in the database.
- Remove the obsolete thread-locking for the "CreateDatabase" operation. This code is guaranteed to run BEFORE any other operation in the database.
- Implement the "handlePreparedStatementException" and "closeConnection" methods.
- Improve error-logs.
- Update dependencies.
- Code cleanup.
- Add connectivity with an Impala-database and create a dedicated Controller for future statistics-requests.
- Optimize the "getTestUrls"-endpoint.
- Disable the "reportCurrentTime()" scheduled-task.
- Update dependencies and bump project's version to '1.0.0-SNAPSHOT'.
- Set the logging-appender to "File".
- Code cleanup.
- Change the data-type of the "UrlReport.status" to be "enum StatusType", in order to increase consistency and comparability.
- Change the "Date" datatype in "Payload" to have the SQL's version.
- Fix the project's name inside "settings.gradle".
- Code cleanup.
In order to match the database, now we have a list of Assignments sent through the AssignmentResponse, instead of a single Assignment having a list of tasks.
- Cleanup the members of the "Payload" model (also prepare for database integration).
