- Update dependencies.
2021-12-24 00:25:50 +02:00
Lampros Smyrnaios 33ba3e8d91 - Avoid getting and uploading (to S3), full-texts which are already uploaded by previous assignments-batches.
- 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.

Lampros Smyrnaios 0178e44574 - Increase security by sanitizing the value of the "workerId" before use it in sql-statements. Impala has bugs with some types of PreparedStatements.
- 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.

Lampros Smyrnaios a46ab84f10 - Increase the lower and upper limits for the Java Heap Size.
- Update the "ServerBaseURL" to the Public IP Address of the machine which is running the app.
2021-12-06 20:27:39 +02:00
Lampros Smyrnaios dea257b87f - Fix a bug, which caused the get-full-texts request to fail, because of the wrong "requestAssignmentsCounter".
- 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.

Lampros Smyrnaios 15224c6468 Improve performance in the "getUrls"-endpoint, and more:
- 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.

Lampros Smyrnaios 48eed20dd8 - Implement the "getAndUploadFullTexts" functionality. In order to access the S3-ObjectStore from one trusted place, the Controller will request the files from the workers and upload them on S3. Afterwards, the workers will delete those files from their local storage. Previously, each worker uploaded its own files.
- Move the "mergeParquetFiles" and "getCutBatchExceptionMessage" methods inside the "FileUtils" class.
- Code cleanup.
2021-11-30 18:23:27 +02:00
Lampros Smyrnaios 780ed15ce2 - Fix a "databaseLock" bug, which could cause both the payload and attempt inserts and the "mergeParquetFiles" to fail, as the inserts could be executed concurrently with tables-compaction.
- 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.
