Antoine Pitrou commented on ARROW-3877: --------------------------------------- Do we have a use case currently for one-shot decompression without knowing the decompressed length? Compressed files are read using streaming decompression (which is more reasonable for huge data anyway). > [C++] Provide access to "maximum decompressed size" functions in compression > libraries (if they exist) > ------------------------------------------------------------------------------------------------------ > > Key: ARROW-3877 > URL: https://issues.apache.org/jira/browse/ARROW-3877 > Project: Apache Arrow > Issue Type: Improvement > Components: C++ > Reporter: Wes McKinney > Priority: Major > Fix For: 0.14.0 > > > As follow up to ARROW-3831, some compression libraries have a function to > provide a hint for sizing the output buffer (if it is not known already) for > one-shot decompression. This would be helpful for sizing allocations in such > cases -- This message was sent by Atlassian JIRA (v7.6.3#76005)
