331 >: ant test-core -Dtestcase='TestWarcRecordWriter' |
| 45 | 332 |
| 333 Logic is tricky, and there's no easy way in | |
| 334 | |
| 335 Basically, tools/WarcExport.java is launches a hadoop job based on a | |
| 336 hadoop-runnable WarcExport instance. Hadoop will in due course call | |
| 337 ExportReducer.reduce, which will create an instance of WarcCapture | |
| 338 "for each page capture", and call ExportMapper.context.write with that instance (via | |
| 339 some configuration magic with the hadoop job Context). That in turn | |
| 340 uses (more magic) WarcOutputFormat.getRecordWriter, which | |
| 341 (finally!) calls a previously created WarcRecordWriter | |
| 342 instance.write(the capture). | |
| 343 | |
| 344 So to fake a test case, I need to build | |
| 345 1) a WarcRecordWriter instance | |
| 346 2) a WarcCapture instance | |
| 347 and then invoke 1.write(2) | |
| 348 | |
| 349 Got that working, although still can't figure out where in the normal | |
| 350 flow the metadata entry for Response.CONTENT_TYPE gets set. | |
| 351 | |
| 352 Now, add a test that takes a stream of WARC Response extracts and | |
| 353 rewrites their index entries | |

| 48 | 784 Start looking at how we do the merge of cdx_extras.py with existing index |
| 785 | |
| 58 | 786 ====2024-12-19==== |
| 787 | |
| 788 The above test shows 17.6% of entries have an LM value | |
| 789 For a 3 billion entry dataset, than means 530 million LM entries, call | |
| 790 this n. | |
| 791 | |
| 792 Sizes? For a 10% error rate, we need m bits = -n * ln(.1) / ln(2)^2 | |
| 793 | |
| 794 (- (/ (* n (log .1)) (* (log 2)(log 2))) = 2,535,559,358 =~ 320MB | |
| 795 | |
| 796 That's too much :-) Per segment, that becomes possible? | |
| 797 25,355,594 bits =~ 3.2MB | |
| 798 | |
| 799 But maybe it's _not_ too much. One of the python implementations I | |
| 800 saw uses mmap: | |
| 801 | |
| 802 https://github.com/prashnts/pybloomfiltermmap3 | |
| 803 | |
| 804 Build a Bloom filter with all the URIs whose entries have LM value | |
| 805 _and_ a python hashtable mapping from URI to LM and offset (is that | |
| 806 enough for deduping?) | |
| 807 Rewrite one index file at a time | |
| 808 Probe with each URI, if positive | |
| 809 look up in hashtable and use if found | |

| 844 _That's_ encouraging... | |
| 845 Be sure to f.close() | |
| 846 Use BloomFilter.open for an existing bloom file | |
| 847 Copying a file from /tmp to work/... still gives good (quick) lookup, | |
| 848 but _creating and filling_ a file on work/... takes ... I stopped | |
| 849 waiting after an hour or so. | |
| 850 ================ | |
| 851 | |
| 852 | |
| 48 | 853 Try it with the existing _per segment_ index we have for 2019-35 |
| 854 | |
| 58 | 855 Assuming we have to key on segment / file and offset, as reconstructing the |
| 48 | 856 proper index key is such a pain / buggy / is going to change with the year. |
| 857 | |
| 858 Stay with segment 49 | |
| 859 | |

| 866 | |
| 867 So no bogons, not _too_ surprising :-) | |

| 873 | |
| 874 So not viable to paste offset as a key and then sort on command line, | |
| 875 or to load it in to python and do the work there... | |
| 876 | |
| 877 Do it per warc file and then merge? | |
