- Update dependencies.
 2024-04-26 12:54:00 +03:00
Lampros Smyrnaios e2d43a9af0 Upgrade the "processBulkImportedFilesSegment" code: 
1) Pre-calculate the file-hashes for all files of the segment and perform a single "getHashLocationsQuery", instead of thousands
2) Write some important events to the bulkImportReport file, as soon as they are added in the list.
 2024-04-02 14:35:19 +03:00
Lampros Smyrnaios bd323ad69a Avoid a very rare case, where we might get an "IllegalArgumentException" from "Lists.partition()", in case the "sizeOfUrlReports" is <= 3. 2024-03-29 18:12:52 +02:00
Lampros Smyrnaios 08de530f03 Various improvements: 
- Handle the case when "fileUtils.constructS3FilenameAndUploadToS3()" returns "null", in "processBulkImportedFile()".
- Avoid an "IllegalArgumentException" in "Lists.partition()" when the number of files to bulkImport are fewer than the number of threads available to handle them.
- Include the last directory's "/" divider in the fileDIR group of "FILEPATH_ID_EXTENSION" regex (renamed from "FILENAME_ID_EXTENSION").
- Fix an incomplete log-message.
- Provide the "fileLocation" argument in the "DocFileData" constructor, in "processBulkImportedFile()", even though it's not used after.
 2024-03-29 17:23:01 +02:00
Lampros Smyrnaios 1d821ed803 - Prepare version for next release.

- Avoid possible failures from outdated metadata.
 2024-03-14 13:10:54 +02:00

- Fix not counting the failedSegments when an exception was thrown.
- Code polishing.
 2024-03-13 12:15:59 +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 e4540e7f3c Handle the case when a urlReports-sublist does not have any payloads inside. 2024-03-12 14:25:00 +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.
 2024-03-11 19:48:04 +02:00
Lampros Smyrnaios 1048463ca0 - Improve error-handling in "S3ObjectStore.emptyBucket()". 
- Change some log-levels.

- Code polishing.
 2024-02-23 12:39:28 +02:00

Lampros Smyrnaios 3a70b57146 Prioritize the full-text urls over the landing-page ones. 2024-01-15 12:59:50 +02:00

 2023-12-19 23:31:42 +02:00
Lampros Smyrnaios d90ad51609 Add the "shutdownAllWorkersGracefully" and "cancelShutdownAllWorkersGracefully" endpoints, in order to be able to shut them down at once and update them, without shutting down the whole Service. So in this case the bulk-import procedures will continue to work. 2023-11-29 16:45:58 +02:00
Lampros Smyrnaios d20c9a7d2e - Show the original exception thrown by the background-job, not the one thrown in the main-thread, which is useless, except from its message. 
- Reduce the interval for deleting the unhandled assignments to once every 3 days.
- Set the upcoming version.
- Update dependencies.
 2023-11-27 18:19:53 +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
Lampros Smyrnaios 9b1f2c4931 Improve performance and reduce memory usage of the "findAssignmentsQuery": 
- Reorder JOINs and predicates to reduce the computational cost.
- Remove the memory-costly "pu.url" predicates from the "where" clause, as the DB has no empty urls anymore.
 2023-10-31 15:59:48 +02:00
Lampros Smyrnaios db929d8931 - Add a scheduling job to delete assignments older than 7 days. These may be left behind when the worker throws a "SocketTimeoutException" before it can receive the assignments and process them. No workerReport gets created for those assignments. 
- Improve some log-messages.
- Code polishing.
 2023-10-30 12:29:54 +02:00
Lampros Smyrnaios 856c62887d - Make sure the "UTF_8" charset is used, when we get a message from the response-body. 
- Improve some log-messages.
 2023-10-26 11:44:23 +03:00
Lampros Smyrnaios bdf834c439 - Refactor the "shutdown" script to do an orderly-shutdown, by default, by calling the "shutdownService" endpoint. In case a "force-shutdown" is needed, that can be requested with a cmd-argument. 
- Fix not updating the "UrlsController.numOfWorkers" correctly.
- Code polishing.
 2023-10-23 17:19:29 +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).
 2023-10-23 12:21:42 +03:00
Lampros Smyrnaios a7581335f1 - Improve the "getDataForPayloadPrefillQuery". 
- Improve some error-messages.

 2023-10-19 11:59:37 +03:00
Lampros Smyrnaios 40729c6295 Move similar code into the new "ParquetFileUtils.getPayloadParquetRecord()" method. 2023-10-17 12:50:51 +03:00
Lampros Smyrnaios f05eee7569 Improve the names of some methods. 2023-10-16 23:39:43 +03:00
Lampros Smyrnaios def21b991d Improve the UX of the "installAndRun.sh" script. 2023-10-09 17:28:22 +03:00
Lampros Smyrnaios fb2877dbe8 Upgrade the execution system for the backgroundTasks: 
- Submit each task immediately for execution, instead of waiting for a scheduling thread to send all gathered tasks (up to that point) to the ExecutorService (and block until they are finished, before it can start again).
- Hold the Future of each submitted task to a synchronized-list to check the result of each task at a scheduled time.
- Reduce the cpu-time to assure the Service can shut down, by checking if there are "actively" and "about-to-be-executed" tasks, at the same time. Instead of having to rely on the additional checking of the "shutdown"-status of each worker to verify that no active task exist.
- Improve the threads' shutdown procedure.
