Implementation of the paper “Poem: Progressive and Efficient Live Migration in Distributed Database Systems” Poem is a testbed of an OLTP distributed database management system (DBMS).
To ensure that the code works properly, the server needs to have the following dependencies:
g++ >= 6.4.0
Boost = 1.6.1
jemalloc >= 5.2.1
nanomsg >= 1.1.5
libevent >= 1.2
libibverbs
To build the database.
make clean
make -j
Poem configurations can be changed in the config.h file. Please refer to README for the meaning of each configuration. Here we only list several most important ones.
NODE_CNT : Number of server nodes in the database
THREAD_CNT : Number of worker threads running per server
WORKLOAD : Supported workloads include YCSB and TPCC
MAX_TXN_IN_FLIGHT : Maximum number of active transactions at each server at a given time
DONE_TIMER : Amount of time to run experiment
Configurations can also be specified as command argument at runtime. Run the following command for a full list of program argument.
./rundb -h
The Poem can be run with
./rundb -nid[N]
./runcl -nid[M]
where N and M are the ID of a server and client, respectively
The ifconfig.txt file records the IP address that machine you want to test.
Here is an example of this file:
10.77.110.148
10.77.110.148
And run with
./rundb -nid0
./rundb -nid1
