Added performance improvement for datetime field parsing

[CaptainDredge]

Signed-off-by: Prabhat Sharma [email protected]

Description

This PR adds caching of last used datetime field parser on a shard level in case of no explicit format specified for the datetime field in mapping i.e. for default datetime mapping. This also adds strict_date_time_no_millis as additional formatter in default date time formats to improve the efficiency of formatting for most common log date format of yyyy-MM-dd'T'HH:mm:ssZ

This PR also adds printFormat to control format for string conversion of epochs back to datetime during search requests

1. Are there any real scenarios where canCacheLastParsedFormatter would be set to false? If not, then it should not be exposed in the function arguments and the feature flag would toggle formatter cache on/off.
2. Does it make sense to cache multiple (all possible) formatters in a concurrent map with a max size instead of just the last one? It feels like there's only N possible formats ever used and if the lookup is always cheaper than the new formatter construction then we can end up with predictably better performance regardless of the mix in the data formats.

@dblock if I understood the change, the "cache" in scope of this pull request is really reoder: the list of the parsers is iterated over and in case of successful parsing, this parser moves to the begging of the parsers list (so next parsing attempt will start with it). But we don't actually "cache" or construct the parsers (@CaptainDredge please correct me if I am wrong)

Ok, you're right, I misunderstood! So my next dumb question is: doesn't this potentially cause the wrong parser to be applied by assuming that the data is all the same format? If for doc 1 parser 1 fails, and doc 2 succeeds, you could very well had row 2 parser 1 succeed, but with the cache it will fail. I do get it that it's rare to put data with different formats in multiple documents, but it's entirely possible.

If I am correct (I am sure you'll show me how I misunderstood this again :) then the only 100% reliable approach is that the caller can hint to the parser to use.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-9567-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 2965e69aff83b702d46d1d630998cbf3ef7ebca5
# Push it to GitHub
git push --set-upstream origin backport/backport-9567-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-9567-to-2.x.

@reta I needed to add synchronisation while updating list to maintain data consistency for eg. there could've been a race condition where the formatter is removed but not yet added and in the meantime another thread tried to parse through the list which doesn't contain that formatter. Can we merge this in main now?

@CaptainDredge I think there are problem with last minute changes, please correct me if I am wrong here (commented on problematic places).

[CaptainDredge]

@reta yes I've tried to address your concerns, see if the responses are satisfactory otherwise I can raise separate PR for any suggested changes by you asap

@CaptainDredge

I am seeing multiple tests failure showing up while parsing the date time data value. Also these are happening for non-concurrent path as well. It seems to be related to this PR, can you please take a look ?

@sohami yes, this change has introduced the issue that was fixed shortly after by #10385

[CaptainDredge]

@sohami as @reta mentioned these should've been fixed by #10385 but I'll try reproducing these flaky tests locally and will try to resolve any issues but just wondering if you've any idea on how frequently these tests are failing because I don't see other PRs referring above issues to get an idea on number of failures

Not sure about the frequency, but it started showing up last week only across multiple test cases. Earlier the thought was it has probably something to do with concurrent search. On looking further, found correlation with this change hence raised it here. You can check the run time in the shared CI links and see if your change was already merged in by then. Or try running locally in loop and see if it repros.

@CaptainDredge Any luck with your manual local run. Are these still failing ? if not, can you please close these issues ?

[CaptainDredge]

@sohami I tried reproing locally by running these in loops for few iterations but wasn't lucky enough to hit failure. I'll close these issue outs and if other PRs reports failure, then will put more effort on these
