> To support JSON schema to TypeInformation conversion
> -----------------------------------------------------
>
> Key: FLINK-8630
> URL: https://issues.apache.org/jira/browse/FLINK-8630
> Project: Flink
> Issue Type: Sub-task
> Components: Streaming Connectors
> Reporter: Xingcan Cui
> Assignee: Timo Walther
> Priority: Blocker
> Fix For: 1.5.0
>
>
> To support (FLINK-8558), we need to generate a \{{TypeInformation}} from a
> standard [JSON schema|http://json-schema.org/] (and maybe vice verse). There
> are some problems to be discussed, e.g., how to handle JSON {{Number}} type.
> One option would be we always return a specific type, which can be configured
> to be double or BigDecimal, for it.
