 2024-03-14 13:59:23 +02:00

 2024-02-07 18:34:28 +02:00
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).

- Code polishing.
 2023-07-13 18:32:45 +03:00
Lampros Smyrnaios 4c3e2e6b6e - Fix not using actual the "currentAssignmentsBatch" of the workerReport itself, when creating the parquetFileNames and when reporting to the user the initialization of the "addition of the workerReport". 
- Code polishing.
 2023-06-27 16:08:01 +03:00
Lampros Smyrnaios 3988eb3a48 - Use a separate HDFS sub-dir for every assignments-batch, in order to avoid any disrruptancies from multiple threads moving parquet-files from the same sub-dir. Multiple batches from the same worker may be processed at the same time. These sub-dirs are deleted afterwards. 
- Treat the "contains no visible files" situation as an error. In which case the assignments-data is presumed to not have been inserted to the database tables.
- Code polishing/cleanup.
 2023-05-27 02:36:05 +03:00
Lampros Smyrnaios 2b50e08bf6 - Handle the case, were multiple threads may load the same HDFS directory to a database table, thus causing the "directory contains no visible files"-SQLException. 
- Improve the values of the delays for some scheduledTasks.
- Improve elapsed time precision for the "lastAccessedOn" metadata of the workerReports.
- Code polishing.
 2023-05-25 00:34:36 +03:00
Lampros Smyrnaios f51a34138f - Use separate HDFS subdirectories for each worker in order to avoid seeing exceptions about "empty hdfs directory" when "loading" data to the database, because one worker has loaded data generated by multiple workers (since we use only 1 load operation for multiple parquet files). 
- Store each worker's info in a hash-table, in order to efficiently know if we need to create new hdfs subdirectories. Also, this will help to issue "shutdown" requests to the workers in the future, as well as to know which worker has shutdown.
 2023-05-15 13:12:20 +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 8381df70c6 - Improve performance of uploading parquet-files to HDFS. 
- Add some logs.
- Code polishing.
 2023-05-11 19:40:48 +03:00
Lampros Smyrnaios 992d4ffd5e - Add the time-zone in the logs. 
- Change some log-levels to "trace", although most of them are still disabled.
 2023-05-11 03:10:53 +03:00

 2023-04-10 22:28:53 +03:00
Lampros Smyrnaios c39fef2654 Upgrade payload-table to payload-view which consists of three separate payload tables: "payload_legacy", "payload_aggregated" and "payload_bulk_import". 2023-04-10 15:55:50 +03:00
Lampros Smyrnaios 4280f89296 - Set the default value of the "isTestEnvironment" property to "true", in order to avoid undesired outcomes in the production db.

Lampros Smyrnaios 8893662a81 Refactor the UrlsController: a) offload the business-logic to the dedicated "UrlsService" and b) move the "checkParquetFilesSuccess()"-method to "ParquetFileUtils". 2023-02-21 15:36:35 +02:00
Lampros Smyrnaios f89730f196 Improve documentation. 2023-01-27 14:31:07 +02:00

- Code polishing.
 2023-01-18 13:38:05 +02:00
Lampros Smyrnaios 8876089022 - Use Facebook's [**Zstandard**](https://facebook.github.io/zstd/) compression algorithm, which brings very big benefits on compression rate and speed. 
- Update the minIO dependency.
- Code polishing.
 2023-01-10 13:34:54 +02:00

- Improve error-checking and exception-handling in some "S3ObjectStore"-methods.

- Code polishing.
 2022-12-15 14:04:22 +02:00
Lampros Smyrnaios bfdf06bd09 - Apply error-checking on individual CallableTasks and in tasks-batches related to the creation and upload of all the data related to the "attempt" and "payload" table. So, if no data could be uploaded for one or both tables, no "load"-queries will be executed for that/those tables. 
- Catch the more general "Exception", inside "FileUtils.mergeParquetFiles()", in order to be certain that the "SQLException" can also be caught.
- Code polishing.
 2022-12-09 12:46:06 +02:00
Lampros Smyrnaios 0209d24068 - Change the parquet compression from "Snappy" to "Gzip", as there is an unhandleable exception when the app is running inside a Docker Container and uses the "Snappy" compression. 
- Code polishing.
 2022-12-08 16:28:41 +02:00
Lampros Smyrnaios c8baf5a5fc - Fix not finding the parquet-schema files when the app was run inside a Docker Container. 
- Update the "namespaces" and the "names" inside the parquet schemas.
- Code polishing.
 2022-12-08 12:16:05 +02:00
Lampros Smyrnaios b0c57d79a5 - When the Controller cannot retrieve any assignments from Impala (without an error), return an HTTP-"MULTI_STATUS" with an empty "AssignmentsResponse", instead of an "INTERNAL_SERVER_ERROR". 
- Fix an error-message.
 2022-12-05 16:44:00 +02:00
Lampros Smyrnaios 577ea983e8 - Improve some log-messages. 
- Set some optimization settings for gradle.
- Fix error-handling in "installAndRun.sh".
- Update dependencies.
 2022-11-30 16:28:39 +02:00
Lampros Smyrnaios 6226e2298d - Upgrade the results-loading process: Instead of making thousands of sql-insert requests to Impala now we write the results to parquet files, upload them to HDFS and then import the data into the Impala tables with just 2 requests. This results in a huge performance improvement. 
One side effect of using the parquet-files, is that the timestamps are now BIGDECIMAL numbers, instead of "Timestamp" objects, but, converting them to such objects is pretty easy, if we ever need to do it.
- Code polishing.
