Request router for OLTP PostgreSQL sharding

structure of directry build

 build -|
        | --- tmp  -| # temp directory for shards/router data store
                    |
                    | - shard1 -pg shard1 data folder(not pathed or something)
                    |
                    | - shard2 -pg shard2 ---/*/----
                    |
                    | - mdb_router router database with mdb_router extension

how to start

make PG_CONFIG=/home/reshke/bins/pgsql/bin/pg_config clean prepare compile-extension cluster-up

Current problems:

bad memory management
no metadata consistency control
shared memory structures invalidates after restart
we need to use HTAB to avoid linear search in list

TPCC BENCH SQL CAN BE FOUND IN ./cool-sql folder

execute ddl on each shard and then load some data using router

WHAT DO WE NEED FOR TPCC

DDL routing?

RUN TPCC

make PG_CONFIG=/home/reshke/bins/pgsql/bin/pg_config CONFIG_OPTS='-t=yes' clean compile-extension cluster-up 
./tpcc.lua --pgsql-user=routing_user --pgsql-db=lolkek1 --time=360 --threads=12 --report-interval=1 --tables=1 --scale=5 --use_fk=0 --trx_level=RC --db-driver=pgsql --pgsql-port=6432 --pgsql-host=localhost prepare
