TablePlus V1.0 Build 70 _HOT_
In previous sections we were able to make improvements in our searchalgorithms by taking advantage of information about where items arestored in the collection with respect to one another. For example, byknowing that a list was ordered, we could search in logarithmic timeusing a binary search. In this section we will attempt to go one stepfurther by building a data structure that can be searched in\(O(1)\) time. This concept is referred to as hashing.
TablePlus v1.0 Build 70
Retool is a web-based tool for building internal tools and applications on top of your data. It connects to all modern databases (Postgres, MySQL, MongoDB, and even Oracle) and any REST API, as well as third-party APIs like Stripe and Twilio.
Retool gives you a complete set powerful building blocks for building internal tools: Assemble your app in 30 seconds by dragging and dropping from 50+ pre-built components. Connect to Postgres and dozens of data integrations and anything with a REST or GraphQL API. Get started for free?
When a ROW_FORMAT option is not specified explicitly or when ROW_FORMAT=DEFAULT is used, any operation that rebuilds a table also silently changes the row format of the table to the format defined by innodb_default_row_format. For more information, see Defining the Row Format of a Table.
innodb_fill_factor defines the percentage of space on each B-tree page that is filled during a sorted index build, with the remaining space reserved for future index growth. For example, setting innodb_fill_factor to 80 reserves 20 percent of the space on each B-tree page for future index growth. Actual percentages may vary. The innodb_fill_factor setting is interpreted as a hint rather than a hard limit.
Online ALTER TABLE operations that rebuild the table also create an intermediate table file in the same directory as the original table. The innodb_tmpdir option is not applicable to intermediate table files.
The innodb_tmpdir option was introduced to help avoid overflowing a temporary file directory located on a tmpfs file system. Such overflows could occur as a result of large temporary sort files created during online ALTER TABLE operations that rebuild the table.
In replication environments, only consider replicating the innodb_tmpdir setting if all servers have the same operating system environment. Otherwise, replicating the innodb_tmpdir setting could result in a replication failure when running online ALTER TABLE operations that rebuild the table. If server operating environments differ, it is recommended that you configure innodb_tmpdir on each server individually.

This heritage building, the second oldest on the St. Lawrence campus and on the National Register of Historic Places, is divided into two large distinctive rooms; the Cole Reading Room and the Feinstone Room. Both rooms were recently renovated owing to the generosity and vision of Laurentian donors. An ADA accessible restroom is now located on the main floor.
Large multi-purpose room with sound/projection booth and portable stage for movies, lectures, comedians, performers, etc. This space can be reserved by groups with a particular purpose in mind, but not closed off to students, faculty and staff who are in the building.
It hasn't all been good. The 2000s got us XML databases. But our industry atoned by building some great columnar databases during the same time. By the 2010s, we saw dozens of large-scale, open-source distributed database projects come to market. Now anyone can spin up a cluster and query terabytes of data.
I got interested in these kinds of applications because I build databases. I wrote BoltDB, which is a popular embedded K/V store in the Go ecosystem. BoltDB is reliable and, as you'd expect from an in-process database, it performs like a nitro-burning funny car. But BoltDB has limitations: its schema is defined in Go code, and so it's hard to migrate databases. You have to build your own tooling for it; there isn't even a REPL.
Or, think of it this way: you can build a Remix application backed by Litestream-replicated SQLite, and, while it's running, crack open the database using the standard sqlite3 REPL and make some changes. It'll just work.
But wait, there's more. We've effectively eliminated per-query latency. Our application is fast, but it's also simpler. We can break up larger queries into many smaller, more manageable queries, and spend the time we've been using to hunt down corner-casey N+1 patterns building new features.
My claim is this: by building reliable, easy-to-use replication for SQLite, we make it attractive for all kinds of full-stack applications to run entirely on SQLite. It was reasonable to overlook this option 170 years ago, when the Rails Blog Tutorial was first written. But SQLite today can keep up with the write load of most applications, and replicas can scale reads out to as many instances as you choose to load-balance across.
