grpc_api_address = "127.0.0.1:9101"

[raft_config]
id = 1
single = true
raft_dir = "metadata/datas"

2.2 Start the databend-meta​

./databend-meta -c ./databend-meta.toml > meta.log 2>&1 &

2.3 Check databend-meta​

curl -I  http://127.0.0.1:8101/v1/health

Check the response is HTTP/1.1 200 OK.

databend-query.toml

[query]
# For admin RESET API.
admin_api_address = "127.0.0.1:8001"

# Metrics.
metric_api_address = "127.0.0.1:7071"

# Cluster flight RPC.
flight_api_address = "127.0.0.1:9091"

clickhouse_handler_port = 9001

# Query HTTP Handler.
http_handler_host = "127.0.0.1"
http_handler_port = 8081

tenant_id = "tenant1"
cluster_id = "cluster1"

[meta]
meta_address = "127.0.0.1:9101"
meta_username = "root"
meta_password = "root"

[storage]
# fs|s3
storage_type = "s3"

[storage.fs]

[storage.s3]
# How to create a bucket:
# https://cloud.tencent.com/document/product/436/13309
bucket = "databend-1253727613"
