Get the data type used to store event data and metadata.

Supported data types are:

  • "bytea" - Allows storage of binary strings.
  • "jsonb" - Native JSON type, data is stored in a decomposed binary format that makes it slightly slower to input due to added conversion overhead, but significantly faster to process, since no reparsing is needed.
