core: cache transaction indexing tail in memory #28908
Conversation

Hi Gary, sorry this may be a bit off-topic here. As mentioned in #28907, the I think we may need to cut the link between the rpc module and the txIndexer message flow, maybe in another pr. |
Can you please try it out and to see if any high latency occurs? My hunch is it should be performant enough as But yeah, if we do find there is notable latency introduced by this progress query, I can definitely optimize it a bit further. |

Ok sure. I haven't seen high latency since I applied this PR yesterday |
There was a problem hiding this comment.
I think the change is "ok", but I'm a bit curious why you still read it from db. I mean, the txindexer is the one that writes it to the db, so if you make indexTransactions return lastNum, same on IndexTransactions, then the txIndexer.run could update a field on the indexer with it. And you would not need to read it, except at the very startup.
I'm not saying it must be changed though, if you have some good reason that's fine

It's cheap enough to read a database entry per each indexing run. Otherwise, we need to calculate the tail manually and easier to mess it up tbh. |

Hi, @rjl493456442 . May I ask a question about what is the purpose of moving Are you plan to store the Just a little confused. nothing about this PR> |

@fynnss just for refactoring. |
* params: begin v.1.13.12 release cycle * internal/flags: fix typo (ethereum#28876) * core/types: fix and test handling of faulty nil-returning signer (ethereum#28879) This adds an error if the signer returns a nil value for one of the signature value fields. * README.md: fix travis badge (ethereum#28889) The hyperlink in the README file that directs to the Travis CI build was broken. This commit updates the link to point to the corrent build page. * eth/catalyst: allow payload attributes v1 in fcu v2 (ethereum#28882) At some point, `ForkchoiceUpdatedV2` stopped working for `PayloadAttributesV1` while `paris` was active.

This pull request tries to address issue #28907
From the ticket we can see the
txindexer.reportdominates the CPU usage. Inside of this function, only a single database read is involved. Therefore the first attempt to mitigate the situation is caching thetaildata in memory instead of retrieving it from db.Note, with this change, the indexing progress reported will have a big delay as tail is only updated at the end. It might have bad UX for reporting tx indexing progress, but should be fine.
