Dave Marion commented on ACCUMULO-4062: --------------------------------------- I dont think that guarantee ever existed. A client writes K/V into an object, batch writer in this case, they control the buffer size, write threads, and latency. We guarantee order on retrieval, not insert, to my knowledge. > Change MutationSet.mutations to use HashSet > ------------------------------------------- > > Key: ACCUMULO-4062 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4062 > Project: Accumulo > Issue Type: Improvement > Components: client > Reporter: Dave Marion > > Change TabletServerBatchWriter.MutationSet.mutations from a > {code} > HashMap<String,List<Mutation>> > {code} > to > {code} > HashMap<String,HashSet<Mutation>> > {code} > so that duplicate mutations added by a client are not sent to the server. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
