Migration guide

Query options

The following options’ remain unchanged:

  • autoPage
  • consistency
  • fetchSize
  • hints
  • prepare
  • serialConsistency
  • timestamp

The following option is no longer supported:

  • graphOptions: those options configure DSx specific features, that are not supported in this driver

Client options

The following options remain unchanged:

  • contactPoints
  • keyspace
  • credentials
  • credentials.username
  • credentials.password
  • applicationName
  • applicationVersion
  • encoding.map
  • encoding.set
  • encoding.copyBuffer
  • encoding.useUndefinedAsUnset
  • maxPrepared

The following option implementation has changed significantly, but the meaning of those option remains unchanged:

  • id: Now accepts both uuid and string types. When uuid is provided, it will be passed to the database in standard string representation.

The following options’ default values have changes:

  • encoding.useBigIntAsLong: New default - true (previously - false),
  • encoding.useBigIntAsVarint: New default - true (previously - false)

With the update of encoding options, we encourage usage of the builtin types. The ability to use the driver with types is kept as a legacy option, and may be removed in the future.
