Details

We've received a request from sales that a client has problems with writing their own connector (a kind of CDC) using iproto.

Need to extend and fill gaps in the replication docs:

• Platform > Replication
• Reference > Internals > Binary protocol > Replication requests and responses

The resulting documentation must be complete enough to allow readers use the Tarantool replication mechanism from their code.

Issues

• Complete iproto replication docs #4495
• How-to on iproto replication #4496
• Check replication section for connection with iproto reference #4497
