[jira] Commented: (AVRO-684) Java tool for altering the codec of an
Avro data file stream.
[ https://issues.apache.org/jira/browse/AVRO-684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12924709#action_12924709 ]
Doug Cutting commented on AVRO-684:
-----------------------------------
The codec and deflation level might be specified with '-codec' and '-level', so that the command syntax might be:
recodec [-codec codec] [-level level] [infile [outfile]]
> Java tool for altering the codec of an Avro data file stream.
> -------------------------------------------------------------
>
> Key: AVRO-684
> URL: https://issues.apache.org/jira/browse/AVRO-684
> Project: Avro
> Issue Type: New Feature
> Components: java
> Reporter: Patrick Linehan
>
> An example is worth a thousand words:
> cat infile.avro | avro-tools recodec deflate - - > outfile.avro
> The above example would create a new file, "outfile.avro", with the same contents as "infile.avro". However, the codec of "outfile.avro" would be "deflate", regardless of the codec of "infile.avro".
> Proposed features:
> * The tool should preserve any metadata present in the input file.
> * Supported codecs will be "deflate" and "null".
> * Optionally add support for specifying the deflation level, perhaps with syntax as follows: "deflate:N" where N is the deflation level, e.g. "deflate:4".
> Does this proposal sound reasonable?
