Figure 2 Gria: (1) Transactions read the data written by the previous transactions run in the same worker thread; (2) To achieve serializability, the transactions that suffer inter-group conflict (e.g., T3) and cascading conflict (e.g., T5) are aborted, and there is no write-after-write conflict since the committed transactions update data to different versions. (3) The batch size is auto-scaling based on the number of committed transactions in the previous batch; (4) Within the two batches, the abort rate is 4/9.
