[jira] [Updated] (MINIFICPP-1766) ProcessSession::read can't read zero length flowfiles (DatabaseContentRepository)
[ https://issues.apache.org/jira/browse/MINIFICPP-1766?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Zink updated MINIFICPP-1766:
-----------------------------------
Description:
RocksDbStream::write will not create a key in the db for data with length 0, but RocksDbStream::read will check for the existence of the key even when the length is 0.
We could either
* fix RocksDbStream::write to create an entry in the db even for zero length values or
* fix RocksDbStream::read to return successfully when reading 0 bytes even if there is no corresponding key
was:
