> TikaInputStream copies the input stream locally
> -----------------------------------------------
>
> Key: TIKA-2849
> URL: https://issues.apache.org/jira/browse/TIKA-2849
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.20
> Reporter: Boris Petrov
> Assignee: Tim Allison
> Priority: Major
> Fix For: 1.21
>
>
> When doing "tika.detect(stream, name)" and the stream is a "TikaInputStream",
> execution gets to "TikaInputStream#getPath" which does a "Files.copy(in,
> path, REPLACE_EXISTING);" which is very, very bad. This input stream could
> be, as in our case, an input stream from a network file which is tens or
> hundreds of gigabytes large. Copying it locally is a huge waste of resources
> to say the least. Why does it do that and can I make it not do it? Or is this
> something that has to be fixed in Tika?
