• passwd: required string db password（example: DB_PASSWD）
• database：required string database name（example：DB_DATABASE）

Server config

• node_urls: required string full node uri（example: tcp://127.0.0.1:26657, tcp://127.0.0.2:26657, ...）

• worker_num_create_task: required int the maximum time (in seconds) that create task are allowed （default: 1 example: 1）

• worker_num_execute_task: required int the maximum time (in seconds) that synchronization TX threads are allowed to be out of work（example: 30）

• worker_max_sleep_time: required int num of worker to create tasks(unit: seconds)（example: 90）

• init_connection_num: required int client pool config idle connection

• bech32_acc_prefix: option string block chain address prefix（default: `` example: iaa）

• chain_block_interval: option int block interval; default 5 (example: 5)

• behind_block_num: option int wait block num to handle when retry failed; default 0 (example: 0)

• promethous_port: option int promethous metrics server port

• only_support_module: option string setting only support module tx sync,default support all module (default: `` example: bank,nft)

• is_json_rpc_protocol: option string whether use json rpc protocol to connection with full node(default: false)

• chain_id: option string setting collection name by chain_id

Note:

synchronizes cosmos data from specify block height(such as:17908 current time:1576208532) At first,stop the cosmos-sync and create the task. Run:

db.sync_task.insert({
    'start_height':NumberLong(5000000),
    'end_height':NumberLong(0),
    'current_height':NumberLong(0),
    'status':'unhandled',
    'worker_id' : '',
     'worker_logs' : [],
    'last_update_time' : NumberLong(0)
})
