Is the MMDB writer thread safe?

[mandar-01]

I am planning to concurrently insert data into MMDB using go routines. Each routine will read data from a source and insert it to the writer object. Once all ingestion is done, I am planning to save the MMDB file. Here is how I have defined the writer:

writer, err := mmdbwriter.New( mmdbwriter.Options{ IncludeReservedNetworks: true, RecordSize: 32, }, )

Can I invoke writer.InsertFunc() from multiple go routines?

No, it is not thread safe. You would need to guard it with a mutex.
