Hello.
I am trying to understand the Definitive Guide and would appreciate if someone can help me out clarifying my thoughts.
I would like to ask two questions.
[1] In the book it says ,
Elasticsearch added a translog, or transaction log, which records every operation in Elasticsearch as it happens. With the translog, the process now looks like this:
In the segment merging process, is it first recorded in the translog and then data are flushed to the disk?
[2] If yes, is the number of operations and size of operation result for segment merging included in below section for Node Stats API ?
"translog" : {
"operations" : 9245364,
"size_in_bytes" : 10886196986
},
