Dave Marion commented on ACCUMULO-1495: --------------------------------------- Hey [~ctubbsii] : What about moving the major compactor process outside of the tablet server as an initial step? > Host multiple read-only versions of tablets for query performance > ----------------------------------------------------------------- > > Key: ACCUMULO-1495 > URL: https://issues.apache.org/jira/browse/ACCUMULO-1495 > Project: Accumulo > Issue Type: New Feature > Reporter: Christopher Tubbs > > It might be worth providing read-only views of tablets on multiple servers, > while writes go to a single authoritative server. This could improve query > performance in some cases. > Some things to consider: > # Consistency: can I read what I've just written? > # Configuration: how many copies? > # Configuration: how long between syncs? > # Performance: locality, number of file replicas > Variation: > Permit multiple hosting only on tables that have been locked for writes > (useful with a strictly enforced clone-and-lock feature). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
