Thanks for posting this!
I wondered while reading the proposal whether you've considered the
model used by Bigtable  where you can have "compactions" or
re-indexing in an incremental manner. You can then do the trigraph
indexing be done quickly, and maintain different versions of the
trigraph indexes that can be concurrently searched while compactions
are happening in the background as new changes are committed through
the LSP API. This will always be a trade-off, but merging the trigraph
indices can happen independently without resorting to mutating the

The goal is to improve overall Clangd performance by reducing the latency of different kinds of symbol search queries, such as the ones used for code completion. The plan is to follow the proposed design and replace existing implementation by the end of September.
