RTO connection settings via Real-Time SDK ETA API

We have developed an interface to RTO using the Real-Time SDK ETA API to replace Legacy Protocol Converter.

When connecting to RTO what are the recommended connection settings for:

rsslConnectOptions.pingTimeout
rsslConnectOptions.guaranteedOutputBuffers
rsslConnectOptions.numInputBuffers
rsslConnectOptions.sysSendBufSize
rsslConnectOptions.sysRecvBufSize

rsslConnectOptions.tcpOpts.tcp_nodelay

Should compression be used on the connection to RTO, if yes, ZLib or LZ4

Are there any guidelines documented anywhere on recommended connection settings?

Thank you for reaching out to us.

For the settings, it is better to refer to the ETA consumer example in the package or the ETA Consumer - Connecting to the LSEG Real-Time Optimized with Authentication Version 2 tutorial.

We don’t provide recommended connection settings because they vary based on the application’s purpose and behavior. However, you can make these settings configurable so you won’t need to recompile the code whenever you want to change their values.

In the LPC that is being replaced by ETA application, the following parameters are set in the lpc.cnf config file:

lpcsecureConnectioncompressionType: 1
lpcsecureConnectionguaranteedOutputBuffers : 200
lpcsecureConnectionnumInputBuffers : 10
lpcsecureConnectionpingTimeout : 30
lpcsecureConnectiontcpNoDelay : False
lpcsecureConnectiontcpRecvBufSize : 2048000
lpcsecureConnectiontcpSendBufSize : 2048000
lpcsecureConnectiontryNextHostTime : 25

Should similar settings be used in our ETA application?
Should compression be used for the RTO connection, or should this depend on the bandwidth of connection to RTO?

Yes, you can apply those values to ETA.

I checked and found that RTO forces the compression type to LZ4 so it will override the compress type setting to LZ4. You may contact the RTO support team directly via LSEG Support to confirm this.
