PI Adapters should accept a StreamID longer than 100 characters when writing to PI WebAPI OMF endpoint

Currently a StreamId cannot have more than 100 characters because of a limitation in PI Cloud for this type of object. Nevertheless for PI Cores and PI Data Archive, the PI tag limit of characters is 1024. PI Adapters when writing to a PI WebAPI OMF endpoint should accept StreamID with more than 100 characters length to take into account a future migration path for customers currently using PI Connectors and working with existing PI tags with long tag names.

    Hi, 100 characters is to small regarding our tag naming convention, I would appreciate to grow this field. Thanks

    Does anything other than the tag name go in the StreamID? I'm curious as to how many of those 100 characters are actually available for the tag name.
