Gregory Lepore commented on TIKA-4198:
--------------------------------------
For this set of data from the Bureau of Land Management it appears that the
blobs are just in data and geom, but I wouldn't want to assume that that is the
format of other agencies data. However, if it's true that the agencies are just
entering text and it's getting converted to blobs, then I would want them
removed from wherever they are in the GPKG file.
> Skip blob fields in geopkg files

> Key: TIKA-4198
> URL: https://issues.apache.org/jira/browse/TIKA-4198
> Project: Tika
> Issue Type: Improvement
> Reporter: Tim Allison
> Priority: Minor
>
> Some geopkg tables store "geom" information in blob fields, starting with
> magic: 47 50 00...
> By default Tika handles blobs as embedded files. This can cause serious
> resource waste on geopkg files that contain hundreds of thousands of rows
> with a geom field.
> We should create a new parser for geopkg that subclasses the sqlite parser
> and skips blobs from the geom fields by default.
