dynamodb
The DynamoDB driver supports a basic set of commands as specified at Amazon DynamoDB Docs.
Activity Parameters
The activity parameters for this driver are basically properties for the DynamoDB driver. If any of these are not specified, then they are not applied to the client builder, thus the default is whatever it is for the native client.
region
- The region which the driver should connect to. This is the simplest way to configure the rest of the client, since defaults are automatically looked up for the region. This is the only option that is required.endpoint
- The endpoint for the region. Do not specify this if you have already specified region.signing_region
- The signing region for the client. You do not have to specify this if you specified region.client_socket_timeout
- adjust the default for the client session. (integer)client_execution_timeout
- adjust the default for the client session. (integer)client_max_connections
- adjust the default for the client session. (integer)client_max_error_retry
- adjust the default for the client session. (integer)client_user_agent_prefix
- adjust the default for the client session. (String)client_consecutive_retries_before_throttling
- adjust the default for the client session. (integer)client_gzip
- adjust the default for the client session. (boolean)client_tcp_keepalive
- adjust the default for the client session. (boolean)client_disable_socket_proxy
- adjust the default for the client session. (boolean)client_so_send_size_hint
- adjust the default for the client session. (integer)client_so_recv_size_hint
- adjust the default for the client session. (integer)
