Jacques Nadeau commented on DRILL-3987:
---------------------------------------
Some additional thoughts:
packages (both codegen and code)
org.apache.drill.common.types.TypeProtos (type stuff from protoc)
org.apache.drill.exec.vector
org.apache.drill.exec.vector.complex
org.apache.drill.exec.vector.complex.impl
org.apache.drill.exec.vector.complex.reader
org.apache.drill.exec.vector.complex.writer
Classes
org.apache.drill.exec.proto.SchemaUserBitShared.SerializedField
org.apache.drill.exec.util.CallBack
org.apache.drill.exec.memory.BufferAllocator
io.netty.buffer.DrillBuf
Need a Basic version of VectorContainer (probably without the VectorWrapper and
VectorAccessible)
Need to subdivide SchemaPath/MaterializedField.
Need to extract OutOfMemory and some other exceptions
What do to with holders...
We probably need to extract some DrillBuf concepts externally (e.g.
buffermanager)

> I'd like to start by looking at an extraction that pulls out the base
> concepts of:
> buffer allocation, value vectors and complexwriter/fieldreader.
> I need to figure out how to resolve some of the cross-dependency issues (such
> as the jdbc accessor connections).
