Jark Wu updated FLINK-14824:
----------------------------
Fix Version/s: 1.10.0
> Improve schema derivation for formats
> -------------------------------------
>
> Key: FLINK-14824
> URL: https://issues.apache.org/jira/browse/FLINK-14824
> Project: Flink
> Issue Type: Sub-task
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
> SQL / API
> Reporter: Jark Wu
> Priority: Major
> Fix For: 1.10.0
>
>
> Currently, one also needs to define a schema for formats in DDL or decriptor
> API. For JSON, CSV and OldCsv, we already supported {{derive.schema=true}} to
> get the schema from table schema. But for Avro format, a user has to pass an
> Avro schema file or define the format schema explicitly via {{avro.schema}}.
> We can think of if we can drop {{avro.schema}} and make
> {{derive.schema=true}} as the default behavior.
