Database indexing
We analyze and set up database indexes for your real queries: add missing ones, remove useless ones, design composite indexes. So reads become fast and the DB stops doing heavy full scans. Honestly upfront: indexes speed up reads, but it is a trade-off — they slow writes and take space; wrong indexes harm, so we decide by real queries, not 'on everything'.
Database indexing — overview
Database indexing is a project: we analyze real queries and execution plans (EXPLAIN), find where indexes are missing (full scan, slow selects/sorts/joins), design correct indexes (single and composite with the right column order), remove unused/duplicate ones, verify the effect. Honestly about the trade-off, this is key: an index is NOT a 'free speedup': it speeds up reads but SLOWS writes (insert/update) and takes disk and memory space; so 'putting indexes on everything' is a mistake, we add only those really needed by your queries. Honestly about the harm of wrong indexes: extra, duplicate or poorly designed indexes waste resources and may go unused (or hinder the planner) — we find and clean them. Honestly about data: we make decisions by REAL queries and data — without them it is guesswork; on small tables indexes may give no effect. Honestly about risk: creating indexes on large tables can temporarily load the DB (we do it carefully, without downtime where possible); we check on test data. Honestly about business: speeding up reads improves response, we do NOT guarantee sales growth by itself. Honestly about access: access to the DB and real queries/logs is needed. An important boundary: this is indexing, not query optimization itself (717 — adjacent, often together), not caching (719/720) and not schema redesign. If indexes are already well set up, the benefit is small. Picture this: instead of 'the DB scans the whole table on every query' — fast index access, without overloading writes. The base price starts from 15,000 ₽ per project; it depends on the number of tables and queries.
Problems we solve
- Queries do a full scan due to missing indexes.
- Slow sorts, selects and joins.
- Many extra/duplicate indexes wasting resources.
- Indexes are set up at random, not for real queries.
What's included in the Database indexing service
- Analysis of real queries and plans (EXPLAIN)
- Finding missing indexes (full scan, sorts, joins)
- Designing single and composite indexes
- Removing unused/duplicate indexes
- Accounting for the read/write/space trade-off
- Careful creation (without downtime where possible)
- A 'before/after' report and check on test data
- Handover and review with you
What you get
- Fast index reads instead of full scan
- Fewer heavy sorts/joins
- Extra indexes that wasted resources removed
- A read/write balance for your queries (sales growth — not guaranteed)
How the work goes: steps
- We collect real queries/logs; collect DB access
- We analyze plans, design needed indexes, clean extra ones
- We check on test data, measure 'before/after', review with you

FAQ
Let's put indexes on all fields for speed?
No, that is a mistake. Indexes speed up reads but slow writes and take space; extra indexes waste resources and may go unused. We add only those really needed by your queries and remove the useless ones.
Will indexes definitely speed up my DB?
Where there is now a full scan on real queries — yes, measurably. But on small tables or with already-good indexes the effect is small. We decide by real queries and data, otherwise it is guesswork.
Won't creating indexes take down the DB?
On large tables creation can temporarily load the DB — we do it carefully, without downtime where possible, and check on test data. We account for and minimize the risk; we do not promise risk-free 'magic'.
