--------------------------------------
Summary: Tika external parsers cannot be turned off without
patching the tika-app-XX.jar
Key: TIKA-1867
URL: https://issues.apache.org/jira/browse/TIKA-1867
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.11
Reporter: Roman Kratochvil
The CompositeExternalParser calls ExternalParsersFactory.create() which always
uses configuration from
org/apache/tika/parser/external/tika-external-parsers.xml. The issue is that
this introduces performance regression as the parser initialization checks for
presence of external commands (ffmpeg, exiftool) and that takes time.
Unfortunately, there is no way how to turn off this functionality without
patching the tika-app JAR -- one has to either change the
tika-external-parsers.xml or remove the whole CompositeExternalParser from list
of services in /META-INF/services/org.apache.tika.parser.Parser.
