 2024-03-22 17:50:55 +02:00

 2024-03-20 15:25:19 +02:00
Lampros Smyrnaios 8f9786de09 Upgrade the algorithm for finding the previously-found fulltexts, based on their md5hash: 
- Use a single query with a list of the fileHashes, instead of thousands of singe-md5hash-check queries (run at most 6 in parallel) which require a lot of I/O.
- Avoid checking multiple times the same fileHash, in case it is related with multiple payloads.
- In case of a database-error, avoid completely losing the full-texts of that worker, instead, continue processing the full-texts.
 2024-03-13 11:28:37 +02:00
Lampros Smyrnaios e20c5d2146 - Add error-handling for the case when no payloads could be associated with a specific url which should have been in the hashMultiMap in "addUrlReportsByMatchingRecordsFromBacklog". 
- Fix not cloning the payload, before changing it and adding it in the "prefilledPayloads"-list; instead, an object-reference was used.

 2023-12-19 23:31:42 +02:00
Lampros Smyrnaios 7f789b8ad0 - If we receive an "UnknownHostException" when uploading to the S3ObjectStore, then skip the current full-texts' batch to leave some time for the network to get unstuck. 
- Code polishing.
 2023-11-22 15:29:18 +02:00

 2023-10-26 11:44:23 +03:00
Lampros Smyrnaios 0c7bf6357b - Improve performance in "FileUtils.addUrlReportsByMatchingRecordsFromBacklog()". 
- Make sure we remove the assignments of all "not-successful", old, worker-reports, even for the ones which failed to be renamed to indicate success or failure, or failed to be executed by the background threads (and thus never reached the renaming stage).

Lampros Smyrnaios c9626de120 Handle the case when the "upload-file-to-S3" operation fails with a "ConnectException". In this case, all remaining upload operations for the files of that particular batch or segment, are canceled. 2023-10-04 13:01:13 +03:00

 2023-09-04 12:46:55 +03:00
Lampros Smyrnaios febe2b212c Upgrade management of failed workerReports: 
- Upon completing processing a workerReport, the name of the json-file will be appended with "successful" or "failed".
- Avoid deleting immediately the failed workerReports.
- Add a scheduling task to process leftover failed workerReports from previous executions of the service, only once, 12 hours after startup, in order for the workers to have participated and filled the "workersInfoMap".
- Add a scheduling task to process leftover failed workerReports from the current execution, regularly.
- Fix not iterating through the workers' subDirs when checking the last-access-time of workerReports.
- Fix not deleting the assignment records from the DB, when a failed leftover workerReport gets deleted.
- Code refactoring.

- Code polishing.
 2023-08-30 17:07:51 +03:00

- Update dependencies.
- Code polishing.
 2023-08-23 16:55:23 +03:00
Lampros Smyrnaios fd1cf56863 - Avoid passing some duplicate publications to the Workers, by post-processing the assignments retrieved from Impala. The assignments may contain duplicate id-url pairs, which have different datasources, since one publication may be connected to multiple datasources. 
- Code polishing.
 2023-07-19 18:31:24 +03:00
Lampros Smyrnaios 8dfb58ee63 Avoid assigning the same publications multiple times to the Workers, after the recent "parallelization enchantment". 
After that enchantment, each worker could request multiple assignment-batches, before its previous batches were processed by the Controller. This means that for each batch that was processed, the Controller was deleting from the "assignment" table, all the assignments (-batches) delivered to the Worker that brought that batch, even though the "attempt" and "payload" records for the rest of the batches were not inserted in the DB yet. So in a new assignments-batch request, the same publications that were already under processing, were delivered to the same or other Workers.
Now, for each finished batch, only the assignments of that batch are deleted from the "assignment" table.
 2023-07-11 17:27:23 +03:00

Lampros Smyrnaios c37f157f51 Split the full-texts-batch's main handling-code to two separate methods, which can be used in parallel by two threads, in the future. 2023-06-14 17:16:38 +03:00
Lampros Smyrnaios 0b1ab5b991 Attempt to recover from serious failures, by individualizing the error-handling for each of the "table-merging" queries. 2023-06-10 02:28:02 +03:00

- Code polishing.
 2023-05-18 17:30:40 +03:00
Lampros Smyrnaios 9412391903 - In test-environment mode, check for already existing file-hashes only in the "payload_aggregated" table, instead of the whole "payload" view. This way the investigation for false-positive docUrls is easier, as we avoid checking against the millions of "legacy" payloads. 
- Improve performance in production, by not creating the string objects for "trace"-logs.
 2023-05-15 12:44:16 +03:00
Lampros Smyrnaios 992d4ffd5e - Add the time-zone in the logs.
