Limits on array size?

Is any limits for array size? is two dimensional arrays possible?

Question asked by an attendee during Putting Complex Data Types to Work. @DeepakMajeti

Answers

  • The collection types (Sets, Arrays) are by default sized to 65k bytes. This value is configurable.
    Multi-dimensional arrays are currently only supported with external parquet tables.

  • How exactly this default collections size limit can be increased to (for example) 400KB (specifically for Vertica 10.0.1)?
    Also, what's the expected impact (if any) on RAM usage and/or disk space usage and/or CPU etc after such increase of this limit?
