What

Let kingshard support following table name format:

table_name_xxxxxxxx
table_name_%0nd # n can be any int number

Why

Now kingshard only supports following table name format:

table_name_%04d
table_name_0000

but in some case, we have following table name format:

table_name_%0nd
table_name_00000001

How

when kingshard tries to rewrite the sql statements, default is using %04d, here i use %0nd, n is the value configured in ks.yaml, here is a sample config:

# schema defines sharding rules, the db is the sharding table database.
schema :
    nodes: [node1]
    default: node1
    shard:
    -
        db : db
        table: tbl
        key: userid
        nodes: [node1]
        type: hash
        locations: [1000]
        table_name_post_fix_length: 8 # if you dont set here, will use default 4, i.e tbl_name_0000
