From both performance and thread safety points of view what is the best
approach for the use / reuse of the following objects:
Tika
ParseContext
Parser
Metadata
The Tika object and/or TikaConfig object should only be created once and
then re-used. Same for any Parser or Detector instances
ParseContext ought to be fine to re-use, but it's such a light-weight
thing I normally create one fresh.
Metadata is normally created from scratch each time - all the entries need
to be removed and recreating is typically a lot less work then removing
everything
Depending on how untrustworth / variable the input you're receiving is,
and the impact of an OOM or similar, you might want to look into using the
Tika Server or Fork Mode or Batch Mode.
