The export file can now be many files, called chunks.
By default still only one chunk is exported.
This function is required in case that the exported files shall be
imported to an elasticsearch/opensearch index. The bulk import function
of elasticsearch/opensearch is limited to 100MB. To make it possible to
import YaCy files, those must be splitted into chunks. Right now we
cannot estimate the chunk size as bytes, only as number of documents.
The user must do experiments to find out the optimum chunk max size,
like 50000 docs per chunk. Try this as first attempt.
You can now import zim files into YaCy by simply moving them
to the DATA/SURROGATE/IN folder. They will be fetched and after
parsing moved to DATA/SURROGATE/OUT.
There are exceptions where the parser is not able to identify the
original URL of the documents in the zim file. In that case the file
is simply ignored.
This commit also carries an important fix to the pdf parser and an
increase of the maximum parsing speed to 60000 PPM which should make it
possible to index up to 1000 files in one second.
because we now start YaCy with a default password (yacy).
This has impact of all function that check the current state of
password-protection that included the empty password situation,
including the warnings to set a password in case that none is set (which
cannot be the case any more).
We still need to set the load in the process because a demand for higher
crawl speed may require to increase the maximum load limit. However,
following the criticism in the bug, we do never reduce the load limit
again.
