Map LOB-columns in DB2 to VARCHAR(32kb) columns in IDAA

At this moment it is not possible to use LOB-columns in the IDAA. This limits our use of the IDAA in several areas where data is registered in LOB-columns. We understand that a full implementation of LOB-columns in IDAA will not happen in (near) future, but that another, limited, variant is possibly an option. Mapping a substantial part of a LOB-column (32kb) in DB2 to a VARCHAR-column in the IDAA. That would help us a lot, as most of our LOB column contents are covered by that size. It is important that the column in DB2 remains a LOB-column and that only the mapping in IDAA will be VARCHAR, so we don't have to do any conversions in DB2 and application. We expect that during the definition and load of a table in and to IDAA LOB-columns are automatically detected and mapped to VARCHAR 32kb. We understand and accept that data longer than 32K will be truncated in the IDAA.
