Xandra v0.13.1 Xandra.SchemaChange View Source

A struct that represents the result of a query that modifies the schema.

This struct has the following fields:

:effect - the type of change involved. It's one of "CREATED", "UPDATED", or "DROPPED".
:target - what has been modified. It's one of "KEYSPACE", "TABLE", or "TYPE".
:options - a map of options that depends on the value of :target:
- if target is "KEYSPACE", the map will have the form %{keyspace: keyspace}
- if the target is "TABLE" or "TYPE", the map will have the form %{keyspace: keyspace, subject: subject} where keyspace is the keyspace where the change happened and subject is the name of what changed (so the name of the changed table or type)
:tracing_id - the tracing ID (as a UUID binary) if tracing was enabled, or nil if no tracing was enabled. See the "Tracing" section in Xandra.execute/4.
