--------------------------------------
Summary: Conditional Mutation with 1000 conditions is slow.
Key: ACCUMULO-1859
URL: https://issues.apache.org/jira/browse/ACCUMULO-1859
Project: Accumulo
Issue Type: Sub-task
Reporter: Keith Turner
Assignee: Keith Turner
Priority: Critical
Fix For: 1.6.0
The random walk test for conditional mutations creates a conditional mutation
with 1000 conditions. I noticed this was really slow.
I did some further testing using MiniAccumulo and was seeing times around
1300ms to 1400ms for this operation (the conditions all checked for absence and
all data for the tablet was in memory).
I traced the problem down to parsing the iterator config. Iterating over the
table config, filtering non iterator props, and parsing was taking a little
more than a 1ms. I modifed TableConfiguration to cache the iterator props and
saw my test times drop to 120ms to 130ms.
