      Description

      The reference manual says the following about memory requirements when streaming columns from the network client - http://db.apache.org/derby/docs/10.7/ref/rrefjavsqlprst.html:

      > For applications using the client driver, if the stream is stored in a column of a type other than LONG VARCHAR or LONG VARCHAR FOR BIT DATA, the entire stream must be able to fit into memory at one time. Streams stored in LONG VARCHAR and LONG VARCHAR FOR BIT DATA columns do not have this limitation.

      I believe this is not true any more. There was a lot of work to reduce the memory requirements for LOBs in Derby 10.2 and Derby 10.3, and I think the specific problem referred to in this section of the manual was fixed in DERBY-550/DERBY-1301.

        Thanks, Kim. I think you're right that we only need to remove that item. I cannot think of anything we need to add. +1 to commit.

        This seems pretty straightforward. Removed the bullet item in question from the topic. Hope this is okay.
