[chef] Re: Latency on search indicies

[Peter Donald < >]

Hi,

Just be warned that the lag can be much more significant. We run the
open source variant of chef for now and have noticed lags of anywhere
between <1s to ~120s between the data being inserted and it being
accessible via search. In most cases we rely on eventual consistency
to catch up but in the cases of directed changes - particularly in our
CD pipeline we insert data bag items and then poll until available
before progressing.

We use search extensively and have a large number of windows nodes
which seems to place pressure on the indexing system. To reduce the
impact we have started to strip out lots of windows ohai data and use
partial search cookbook where possible. That combined wiht a bit more
memory for the chef box has reduced the lag a little.

Not sure if that helps ...
