Timo Walther edited comment on FLINK-22878 at 6/10/21, 10:24 AM: ----------------------------------------------------------------- We found a solution that should solve this problem without touching the general ConfigOption design too much. For ConfigOptions of MapType, we propose to extend the syntax to two possible representations: Current syntax: {code} value.avro-confluent.properties = schema: 1, other-prop: 2 {code} Pro: constant key space Con: difficult to read or modify Additional syntax (but lower precedence): {code} value.avro-confluent.properties.schema = 1 value.avro-confluent.properties.other-prop = 2 {code} It would be made available via `ReadableConfig.get[Optional]`. `ReadableConfig.set` would remain unchanged. was (Author: twalthr): We found a solution that should solve this problem without touching the general ConfigOption design too much.
