Hi guys, While doing pre-analytics we generate hundreds of millions of mutations that result in 1-100 megabytes of useful data after major compaction. We ingest into Accumulo using MR from Mapper job. We identified that performance really degrades while increasing a number of mutations.
The obvious improvement is to do some calculations in-memory before sending mutations to Accumulo. Of course, at the same time we are looking for a solution to minimize development effort. I guess I am asking about micro compaction/ingest-time iterators on the client side (before data is sent to Accumulo). To my understanding, Accumulo does not support them, is it correct? And if so, are there any plans to support this functionality in the future? Thanks Roman Please consider the environment before printing this email. This message should be regarded as confidential.
