I am in the process of implementing partitioning on some existing tables. I
have been asked by management to evaluate the performance impacts of the
changes. I am aware of many of the performance advantages of partitioning:
partition pruning, partition-wise joins and parallel data loads. What I am
concerned about is the additional overhead of inserting data into a
partitioned table. What sort of overhead is associated with partitioned
table inserts? Does determining the correct partition slow insertions? We
are utilizing only range partitions, so hash value computations should not
be a factor. Our application is very insertion intensive. One of the
operations that performs insertions does so synchronously, so any decrease
in insertion performance would be quite visible. Do you have any thoughts or
experiences with this issue. Any performance tests on two similar tables,
one partitioned and the other not? Any input would be appreciated. Thanks.
