Hi, I am reading this https://github.com/forcedotcom/phoenix/wiki/Secondary-Indexing and trying to figure out what is the difference between mutable and immutable index. One difference I figure out is that immutable index is client-managed while mutable index is cp-managed.
I was expecting that, mutable index coprocessor do three things: 1) put new index entry, 2) read base table and get old index value, 3) delete old index value if any. I could not find code for 2) and 3). So am I understanding it wrong, or I did not find the correct code path? Thanks, Wei --------------------------------- Wei Tan, PhD Research Staff Member IBM T.
