Input StreamsΒΆ

A record stream is the generic form of structured data used by SpectX for query processing. The structure (type and constraints) of a record is determined by exported fields in the pattern used to extract and transform parse the raw input data. In the case of querying data from structured formats (AVRO, ROSBAG) the types of fields are converted to SpectX data types. Hence a SpectX record is quite the same as a record in a relational database.

The following commands create a record stream:

An existing record stream can be referred and manipulated by query statements.
