DO NOT MERGE: Make binary string encoding configurable, add support for base64 #770

@sfc-gh-lsembera what do you think about supporting base64 as well? Also, could we do it automatically instead of adding a parameter? |

@sfc-gh-lsembera what do you think about supporting base64 as well?
I am fine with supporting base64, as well. I just don't like the removal of surrounding quotes - we don't do it for any other data type, and I think we shouldn't do it for base64 either.
Also, could we do it automatically instead of adding a parameter?
We cannot do it automatically. Without additional information, we cannot tell if a string is base64- or hex-encoded.

We should not strip surrounding quotes. We don't do it for hex and neither does it work in Snowflake Worksheets.

We need the same test coverage for base64, as we have for hex.

Please add tests to ParameterProviderTest.
Thanks for confirming, then I think this should be a channel level configuration instead of the whole client, take a look at what we did for |
The problem with having the configuration per-channel is that it is not as easily configurable from KC. |
|
@sfc-gh-tzhang @sfc-gh-lsembera, based on the requirement to work with kafka connector, I think this config should apply to the whole client. Also, I suspect that most streaming use cases with embedded binary in Avro messages will be either 100% hex encoded or 100% base64 encoded, based on the particular tooling used in the customer's environment, so the need to support mixed encodings would be less likely. |

Fix PRIMARY_FILE_ID_KEY
V2.2.0 Release
Addresses issue where streaming client receives base64-encoded strings for binary.
Adds new parameter
BINARY_STRING_ENCODINGwhich supports valueshexandbase64. The default value ishex.
