Abstract
A method for execution by a node of a database system includes receiving a first data block, determining data block processing instruction data for the first data block is not indicated in previously received data blocks, and adding the first data block to an unknown purpose data block cache. Prior to elapsing of a storage time window for storage of the first data block, at least one second data block is received that indicates data block processing instruction data for the first data block. The first data block is processed by applying the data block processing instruction data. A third data block is received and is added to the unknown purpose data block cache. The third data block is removed from the unknown purpose data block cache based on elapsing of a storage time window for storage of the third data block.
