The major changes made in this repository:

• added support for Bamboo and its optimizations. Bamboo is a concurrency control protocol proposed in:

    Releasing Locks As Early As You Can: Reducing Contention of Hotspots by Violating Two-Phase Locking
    Zhihan Guo, Kan Wu, Cong Yan, Xiangyao Yu
    link (TBA)

• focused on support for: NO_WAIT, WOUND_WAIT, WAIT_DIE, SILO, IC3
• changed the memory allocation for lock entry to be static
• added support for MCS Lock in addition to mutex and spinlock
• modified test scripts for easier evaluation

Build & Test

To test the database

python test.py experiments/default.json

Configure & Run

Supported configuration parameters can be found in config-std.h file. Extra configuration parameters include:

    UNSET_NUMA        : default is false. If set false, it will disable numa effect by interleavingly allocate data. 
    NDEBUG            : default is true. If set true, it will disable all assert()
    COMPILE_ONLY      : defalut is false. If set false, it will compile first and then automatically execute. 

Options to change/pass configuration:

• Option 1: use basic configurations provided in experiments/default.json. overwrite existing configurations or pass extra configurations through arguments. e.g. python test.py experiments/default.json WORKLOAD=TPCC NUM_WH=1
• Option 2: directly copy config-std.h to config.h and modify config.h. Then compile using make -j and execute through ./rundb
